Christonical

The church fathers and leaders centuries ago formed a group among themselves  to approve a standard rod of measurement before a manuscript or epistles can be accepted sacred, thus become part of the Bible. They called this rule "canon". The Catholic has more books in their Bible than the Protestants do in their Bible because of the controversy arising from the authority of the canon over other sacred writings.

Are we concern which book is canonical?

We are not concerned about the canonicity of any particular book for we are not searching the truth in every book of the Bible. We found the truth in Jesus Christ. The gospel of the Lord Jesus Christ is christonical, approved by the Father and taught by His Son.

The gospel does not need to be canonized before it can be considered sacred and true. His teachings remain the same as they were before. No amendments were made. What the disciples heard and witnessed are what He meant.

All authority is in Christ. His words are the final standard measurement for everybody. His words will pass judgment on everything before Him.  He never relegated the authority of His words to somebody else to take a furlough or an extended vacation. He is ever present at all times.

Matt 28:18-20
 And Jesus came and spoke to them, saying, "All authority has been given to Me in heaven and on earth.
 "Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, "teaching them to observe all things that I have commanded you; and lo, I am with you always, even to the end of the age." Amen.
