If you want to look a modern comparison between Christianity and Buddhism look no further than eastern orthodox such as Fr. Seraphim Rose (he was a Buddhist before he converted) and other American Orthodox monks. Whether there was a conscious influence or not, I remember, back when I was into that kind of thing, listening to various talks by these monks and thinking that they sound very "buddhist". Their teaching on the ego is uncannily similar to some Indian teachings, above and beyond the teachings of their predecessors. The ego is an illusion, that kind of thing. Removal of desire. All very "Buddhist" but of course this stretches back into very early times so it is again unlikely for there to be any real influence. It is interesting to compare though.
