Christ learnt all from India itself its actually Krishna Niti- the rightoues way to lead life which is now called Christianity & some people (pope,etc.) have made some amendments to it for their benefits but still its peaceful religion coz its roots r based on Lord krishna's message to the world. And by the way hinduism is a way of life and not a religion. Thats why people are not after converting people from other religions forcibly. It gives u choices to lead ur life & choice of worship to attain salvation. Also Bhagvad Gita is not a hindu epic its a book which explains about dharma i.e. what a person must do in the various situations he faces in life and the answers to the many questions a common man (in this case Arjuna) asked.There is no where mentioned in it to follow Hinduism only or this particular god only to attain salvation. Its more about what is right and wrong for various situations that is described.
