Hebrews 13:8, "Jesus Christ the same yesterday, and to day, and for ever."Sorry I'm late to the party.......................
Why do I think that Judaism is older than Christianity? Well, for starters, Judaism was around LONG before Jesus came on the scene. Some would try to use the "trinity" argument saying that God, Jesus and the Holy Spirit are one and the same, but if that is the case, why would there be a reason to have 2 different religions? Shouldn't they all be the same?
As far as Jesus, he was born Jewish, and followed the teachings of Judaism, as that was the primary religion in the place and time He was growing up. Matter of fact, there are stories about Jesus debating with the rabbis in the Temple, so that would mean right there that Jewish theology predated Jesus.
Then..............there is the whole thing about Christianity being all about Jesus, with Jesus basically being the founder and the start of the whole Christianity thing.
Judaism was around a LONG time before Christ showed up. Christianity supposedly came from the teachings of Jesus, which basically means that Christianity is an offshoot of Judaism, as well as that Christianity is a much younger religion than Judaism.
John 8:58, "Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am."
John 1:1 & 14, "In the beginning was the Word, and the Word was with God, and the Word was God." "And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth."
John 10:30, "I and my Father are one."
Christ, the Son, is one with the Father and has been with the Father since "the beginning."
