Buddhism certainly spread around the known world quickly & many of its principles appear to have been adopted & included within other traditions. A very good example, is the Hindu Bhagavad Gita, which is primarily a Hindu text but incorporates Buddhist principles about non-attachment. I personally see little evidence Jesus of Nazareth was a Buddhist monk because he did not teach any of the core Buddhist teachings, such as the Four Noble Truths, the Three Characteristics, the Elements, etc. The moral teachings of Jesus of Nazareth are similar to Buddhism but the wisdom teachings are lacking. Buddhist missions already existed in Egypt & Greece at the time of Jesus of Nazareth, which would have adhered to both Buddhist Dhamma & Vinaya. Jesus of Nazareth did not adhere to Buddhist Dhamma & particularly Vinaya. For example, Buddhism spread around the world based on its Vinaya (moral code) of not harming & being aggressive towards other cultures & religions. But the reports of Jesus of Nazareth was he deliberately provoked the Jewish priests, attempted to assert his authority in the Jewish temple and, in short, attempted to reform the Jewish religion. Buddhist monks do not behave in such a manner. Even Buddha made no attempt to reform the common Brahmin religion of his day. Instead, Buddha, the same as Buddhist monks, deliberately sought peaceful co-existence with other religions. Thus, I personally see little evidence Jesus of Nazareth was a Buddhist monk or conducted himself in the manner of a Buddhist. If Jesus of Nazareth studied in India, which he probably did, his views align themselves with Brahminism. Brahma is the 'Father of the All'. Buddha taught the Brahmins radiating love in all directions is the way to Brahma. Therefore, imo, Jesus of Nazareth, if related to Indian religion, was essentially a Brahmin (i.e., Hindu). Regards
