After I read through past post on this subject, I was amazed that "love" was left out of everyone's essentials. It appears to me that the following is John's opinion of the essentials:

1 John 3:21-24
“Beloved, if our heart does not condemn us, we have confidence before God; and whatever we ask we receive from Him, because we keep His commandments and do the things that are pleasing in His sight. This is His commandment, that we believe in the name of His Son Jesus Christ, and love one another, just as He commanded us.”
