I am not quite sure what you mean, but Christianity started with the message of Jesus Christ, approximately 2000 years ago.
it is the Jewish and christainity mixed together
christainity
The christian religion is about two thousand years old.
Christianity is about 700 years older than Islam.
Jesus Christ delivered the spiritual message/teachings but it was Christ's disciples who began the religion known as Christianity.
This isn't a very hard question because its what the u.s is based off of christainity, or any other forms of this religion there all about the same.(in my veiw point)
The word Advent comes from Christainity & Protestantism. I also think that it is atleast 159 years old!
EVERTHING
