Yes, Christianity went through major restructuring in less than 100 years from the date for Jesus' death. First major editing of scripture and adoption of the Old Testament to justify an authoritarian church, then adapting the Pagan festivals to make conversions easier, and reconstituting favorite local gods and godesses as saints, then vicious sectarian warfare and wholesale murder among Christian communities in the name of Jesus and a loving God.

If you love sausage and Christianity, don't see either one made. Probably the Jahova's Witnesses are as close as you'll get to the real thing in this day and age.
