**Sorry to bust your bubble but **if you studied Jesus from a History stand point, you would know that the original and first debates among the “new Christians”, Jews, and many pagons. Was not that Jesus did not exist, but whether or not he was in fact the son of God, or even Divine.
The new Christians of His day confirmed that they believed he was the Son of God. The “Docetists” on the other hand maintained the belief that Jesus only appeared to be Human.
The word Anti Christ is only used in the letters of John where John defined that an anti christ designates anyone who opposes and attempts to subvert the lordship of Jesus, the Christ.
After the death and resurection of Jesus, the early Church was growing fast, converting more and more over each and every day, witnessing their personal (actual) first hand experience as living witnesses of the truth of Jesus Christ.
Of course as the Church grew some of the local churches established by the Apostles went astray in their beliefs and that where you see Apostles like Saint Paul write letters back to the peoples and Church commnunities of Cornith see 1st and 2nd Corintheans, Epeshia, and so forth… those letters were written to those newly established churches, correcting them on their mistakes and preaching to them the Truth.
Of course as we go farther out, and before trains, planes, and automobiles, this was harder to control and the Pope had a very hard time over many years as the head bishop of many churches over many lands. Its just a blessing that everyone made it to the counsil of trent, and other counsels through out our 2000 year Church History.
After Luther and the reformation of course we are not arguing the same thing as they did at the time of Jesus on who am I , or who was he? But instead we have a lot of different churches preaching different gospels today with various doctrines of faith.
But for all Christians doesnt the Bible warn us not to add to or take away from the gospel of the Lord. Jesus Christ selected 12 men to be His Apostles and taught them and left them His Church and one in particular the Keys as Pope, St. Peter, he gave them all the power to forgive and retain sin here on earth. Jesus set up our Church. And for 2000 plus years we have been fighting and correcting every heresy that has come a long, at first with the Docetists and now all those protesters that are Protesting the word of God and His Church.
**Again will all due respect Sir, take a hard look at history before you claim that **“Christians have never been able to offer convincing proof to the many doubters in the world who just do not believe that Jesus (pbuh) ever lived.”
