What doctrine became a centerpiece of Christian faith and preaching and the basis on which early Christianity proclaimed Jesus as Christ Explain its significance Be specific?

Answer 1

I assume from your comments, you have never actually read biblical text. Christianity is not built upon some doctrine which was defined by men, its based upon law as defined by our Creator (Father), you will find the details given in the book of Leviticus and again in Deuteronomy. The law was given to Moses and to the house of Aaron (priest line) it was documented by the scribes of Israel on scrolls.

Read the the second chapter of the book of Ezekiel, if you have the ability to understand, you will understand our Fathers word from that testament. Jeremiah 32, 36, 43 and 45 will help you understand the relationship between a prophet and a scribe assigned to that prophet.

Christ wasprophesied as Immanuel by the prophet Isaiah 7:14, The gospel or good news was the affirmation that Christ was in fact Immanuel as defined by our Father to the prophet Isaiah. Christianity is the fact that Christ became the one and only sacrifice for one and all time for the sins of men (Hebrews 10). The good news is that we as the children of the Lord God, all have the ability to earn eternal life for our soul in the 3rd earth age (2nd Peter chapter 3). Each and every soul (who are not election, has the freedom to choose if they will accept Christ as Immanual, obtain forgiveness for their sins, and continue to abide by our Fathers law in order to obtain eternal life for their soul). That is a very condensed version but it gets to the point. Just remember the decision belongs to the individual and can not be forced. We will all be judged for our decision individually, Revelation chapter 20.

Now this answer is very condensed as there is not enough space on several harddrives to contain all the details to your question, so it is assumed you were looking for a summary with some specifics you could look into on your own.

Answer 2

In the resurrection of Jesus Christ.
