Buddhist influences on Christianity
It is agreed by most scholars that Buddhism was known in the pre-Christian Greek world through the campaigns of Alexander the Great (see Greco-Buddhism and Greco-Buddhist monasticism), and several prominent early Christian fathers (Clement of Alexandria and St. Jerome) were certainly aware of the Buddha, even mentioning him in their works.
There have also been suggestions of an indirect path in which Indian Buddhism may have influenced Gnosticism and then Christianity. Some scholars hold that the suggested similarities are coincidental since parallel traditions may emerge in different cultures.
Despite suggestions of surface level analogies, Buddhism and Christianity have inherent and fundamental differences at the deepest levels, such as monotheism's place at the core of Christianity and Buddhism's orientation towards non-theism.
In the East, the syncretism between Nestorian Christianity and Buddhism was deep and widespread along the Silk Road, and was especially pronounced in the medieval Church of the East in China. There are also historical documents showing the syncretic nature of Christianity and Buddhism in Asia such as the Jesus Sutras and Nestorian Stele.
Suggestions of influence
Will Durant, noting that the Emperor Ashoka sent missionaries, not only to elsewhere in India and to Sri Lanka, but to Syria, Egypt and Greece, first speculated in the 1930s that they may have helped prepare the ground for Christian teaching. Buddhism was prominent in the eastern Greek world (Greco-Buddhism) and became the official religion of the eastern Greek successor kingdoms to Alexander the Great's empire (Greco-Bactrian Kingdom (250 BC-125 BC) and Indo-Greek Kingdom (180 BC - 10 CE)). Several prominent Greek Buddhist missionaries are known (Mahadharmaraksita and Dharmaraksita) and the Indo-Greek king Menander I converted to Buddhism, and is regarded as one of the great patrons of Buddhism. (See Milinda Panha.) Some modern historians have suggested that the pre-Christian monastic order in Egypt of the Therapeutae is possibly a deformation of the Pāli word "Theravāda," a form of Buddhism, and the movement may have "almost entirely drawn (its) inspiration from the teaching and practices of Buddhist asceticism". They may even have been descendants of Asoka's emissaries to the West. It is true that Buddhist gravestones from the Ptolemaic period have also been found in Alexandria in Egypt, decorated with depictions of the Dharma wheel, showing the Buddhists were living in Hellenistic Egypt at the time Christianity began. The presence of Buddhists in Alexandria has led one author to note: "It was later in this very place that some of the most active centers of Christianity were established". The early church father Clement of Alexandria (died 215 AD) was also aware of Buddha, writing in his Stromata (Bk I, Ch XV): "The Indian gymnosophists are also in the number, and the other barbarian philosophers. And of these there are two classes, some of them called Sarmanæ and others Brahmins. And those of the Sarmanæ who are called "Hylobii" neither inhabit cities, nor have roofs over them, but are clothed in the bark of trees, feed on nuts, and drink water in their hands. Like those called Encratites in the present day, they know not marriage nor begetting of children. Some, too, of the Indians obey the precepts of Buddha (Βούττα) whom, on account of his extraordinary sanctity, they have raised to divine honours."
Nicolaus of Damascus, and other ancient writers, relate that in AD 13, at the time of Augustus (died AD 14), he met in Antioch (near present day Antakya in Turkey just over 300 miles from Jerusalem) an embassy with a letter written in Greek from the Southern India Pandya Empire was delivered while Caesar was in the Island of Samos. This embassy was accompanied by a sage who later, naked, anointed and contented, burnt himself to death at Athens. The details of his tomb inscription specified he was a Shramana, "his name was Zarmanochegas", he was an Indian native of Bargosa, and "immortalized himself according to the custom of his country." Cassius Dio  and Plutarch  cite the same story. Historian Jerry H. Bentley (1993) notes "the possibility that Buddhism influenced the early development of Christianity" and that scholars "have drawn attention to many parallels concerning the births, lives, doctrines, and deaths of the Buddha and Jesus".
The suggestion that an adult Jesus traveled to India and was influenced by Buddhism before starting his ministry in Galilee was first made by Nicolas Notovitch in 1894 in the book The Unknown Life of Jesus Christ which was widely disseminated and became the basis of other theories. Notovitch's theory was controversial from the beginning and was widely criticized. Once his story had been re-examined by historians, Notovitch confessed to having fabricated the evidence.
Rejections of influence
Most scholars agree that there is no historical evidence of any influence by Buddhism on Christianity, Paula Fredriksen stating that no serious scholarly work has placed the origins of Christianity outside the backdrop of 1st century Palestinian Judaism. Leslie Houlden states that although modern parallels between the teachings of Jesus and Buddha have been drawn, these comparisons emerged after missionary contacts in the 19th century and there is no historically reliable evidence of contacts between Buddhism and Jesus.
Other scholars such as Eddy and Boyd state that there is no evidence of a historical influence by outside sources on the authors of the New Testament, and most scholars agree that any such historical influence on Christianity is entirely implausible given that first century monotheistic Galilean Jews would not have been open to what they would have seen as pagan stories. The Macmillan Encyclopedia of Buddhism states that theories of influences of Buddhism on early Christianity are without historical foundation.
Modern scholarship has roundly rejected any historical basis for the travels of Jesus to India or Tibet or influences between the teachings of Christianity and Buddhism, and has seen the attempts at parallel symbolism as cases of 
There are inherent and fundamental differences between Buddhism and Christianity, one significant element being that while Christianity is at its core monotheistic and relies on a God as a Creator, Buddhism is generally non-theistic and rejects the notion of a Creator God which provides divine values for the world.
The central iconic imagery of the two traditions underscore the difference in their belief structure, when the peaceful death of Gautama Buddha at an old age is contrasted with the harsh image of the crucifixion of Jesus as a willing sacrifice for the atonement for the sins of humanity. Buddhists scholars such as Masao Abe see the centrality of crucifixion in Christianity as an irreconcilable gap between the two belief systems.
Post Apostolic Age
Clement of Alexandria referred to Buddhists and wrote:
"Among the Indians are those philosophers also who follow the precepts of Boutta (Βούττα), whom they honour as a god on account of his extraordinary sanctity."— Clement of Alexandria, Stromata (Miscellanies), Book I, Chapter XV
There is ... among the Indians a heresy of those who philosophize among the Brahmins, who live a self-sufficient life, abstaining from (eating) living creatures and all cooked food . . . They say that God is light, not like the light one sees, nor like the sun nor fire, but to them God is discourse, not that which finds expression in articulate sounds, but that of knowledge (gnosis) through which the secret mysteries of nature are perceived by the wise.
Early 3rd–4th century Christian writers such as Hippolytus and Epiphanius write of one Scythianus who visited India around 50 CE, whence he brought the "doctrine of the Two Principles". Scythianus' pupil Terebinthus supposedly presented himself as a "Buddha" ("he called himself Buddas" Cyril of Jerusalem) and became well known in Judaea and was said to have conversed with the apostles and to have brought books back from his trade with India. The same author says his books and knowledge were taken over by Mani, and became the foundation of the Manichean doctrine.
"Terebinthus, his disciple in this wicked error, inherited his money and books and heresy, and came to Palestine, and becoming known and condemned in Judaea he resolved to pass into Persia: but lest he should be recognised there also by his name he changed it and called himself Buddas."— 
Saint Jerome (4th century CE) mentions that the Buddhist belief of Buddha's birth from a virgin as their "opinion [...] authoritatively handed down that Budda, the founder of their religion, had his birth through the side of a virgin," (the Buddha was, according to Buddhist tradition, born from the hip of his mother). It has been suggested that this virgin birth legend of Buddhism influenced Christianity.
Gnosticism refers to a number of small Christian sects which existed in the 2nd-5th centuries, and were rejected by mainstream Christians as heretics. There were some contacts between Gnostics and Indians, e.g. Syrian gnostic theologian Bar Daisan describes in the 3rd century his exchanges with missions of holy men from India (Greek: Σαρμαναίοι, Sramanas), passing through Syria on their way to Elagabalus or another Severan dynasty Roman Emperor. His accounts are quoted by Porphyry (De abstin., iv, 17 ) and Stobaeus (Eccles., iii, 56, 141).
This has given rise to suggestions by Zacharias P. Thundy that Buddhist tradition may have influenced Gnosticism and hence Christianity. Thundy has also considered possible influences through the Jewish sect Therapeutae, which he suggests could have been Buddhists in the first century.
However, Gnosticism was harshly rejected by Christians and c. 180 Irenaeus wrote against them at length in his On the Detection and Overthrow of the So-Called Gnosis, generally called Against Heresies. By the third century Indians were also considered heretics by the Christians who condemned their practices.
Elaine Pagels has encouraged research into the impact of Buddhism on Gnosticism, but she holds that although intriguing, the evidence of any influence is inconclusive. She further concludes that these parallels might be coincidental since parallel traditions may emerge in different cultures.

Cyril of Jerusalem, Sixth Catechetical Lecture Chapter 22-24: "22. There was in Egypt one Scythianus, a Saracen by birth, having nothing in common either with Judaism or with Christianity. This man, who dwelt at Alexandria and imitated the life of Aristotle, composed four books, one called a Gospel which had not the acts of Christ, but the mere name only, and one other called the book of Chapters, and a third of Mysteries, and a fourth, which they circulate now, the Treasure. This man had a disciple, Terebinthus by name. But when Scythianus purposed to come into Judaea, and make havoc of the land, the Lord smote him with a deadly disease, and stayed the pestilence.
23. But Terebinthus, his disciple in this wicked error, inherited his money and books and heresy, and came to Palestine, and becoming known and condemned in Judaea he resolved to pass into Persia: but lest he should be recognised there also by his name he changed it and called himself Buddas. However, he found adversaries there also in the priests of Mithras: and being confuted in the discussion of many arguments and controversies, and at last hard pressed, he took refuge with a certain widow. Then having gone up on the housetop, and summoned the daemons of the air, whom the Manichees to this day invoke over their abominable ceremony of the fig, he was smitten of God, and cast down from the housetop, and expired: and so the second beast was cut off.
24. The books, however, which were the records of his impiety, remained; and both these and his money the widow inherited. And having neither kinsman nor any other friend, she determined to buy with the money a boy named Cubricus: him she adopted and educated as a son in the learning of the Persians, and thus sharpened an evil weapon against mankind. So Cubricus, the vile slave, grew up in the midst of philosophers, and on the death of the widow inherited both the books and the money. Then, lest the name of slavery might be a reproach, instead of Cubricus he called himself Manes, which in the language of the Persians signifies discourse. For as he thought himself something of a disputant, he surnamed himself Manes, as it were an excellent master of discourse. But though he contrived for himself an honourable title according to the language of the Persians, yet the providence of God caused him to become a self-accuser even against his will, that through thinking to honour himself in Persia, he might proclaim himself among the Greeks by name a maniac."
