Folks,

Paul said that Jesus was born of woman (Gal 4.4), descendant of David according to the flesh (Rom. 1:2), had a brother named James, and other brothers who had wifes (Gal. 1.19 and I Cor: 9.5).

(The brothers of Lord; See Gal 1.3; Paul writes "Grace and peace to you from (...) LORD Jesus Christ).

Also, "The Lord Jesus, on the night he was betrayed, took bread" (I Cor. 11:26), Jesus was killed by his countrymen (I Tess. 2.14), and was buried (I Cor. 15:3), and rose on the third day (I Cor. 15).

And,
"the people of Israel. Theirs is the adoption as sons; theirs the divine glory, the covenants, the receiving of the law, the temple worship and the promises. Theirs are the patriarchs, and from them is traced the HUMAN ANCESTRY OF CHRIST, (Rom. 9: 4) .

So, to me, is pretty clear that Paul was referring to a person who really exist, and sojourned on the earth.

And first christians, as far as we know, also believed so. We know about dozens of sects in ancient christianity, which ranged from ebionites , who regardes Christ as just a man; to docetics and marcionites, who believed that Jesus' body wasn't composed of corruptible flesh, but walked in the earth, made disciples, and perform miracles.

However, there is no evidency of any "Christ Myth" heresy to be found in the writings of anti-heresy works of the time (Irenaeus, Tertullian, Hyppolitus...), on the Church Fathers, Apocrypha, Nag Hammady Library....

And, pagan and jew opponents of christianity, alwayr reffered to Jesus as a real person. There no evidence, no indication, that christians believed in mythical Jesus, or that pagans and jews who opossed christianity doubted of Jesus existence.
