1) He is concerned about both. This is Biblical BTW. Either standing alone is severely compromised.
2)
Biblical doctrine IS LOVE. Biblical doctrine is literally God's word of love toward men. Among other things.
But it is knowing doctrine and then teaching it (in love) that constitutes the Great Commission.
What did Jesus do exactly for 3.5 years with the Apostles? TEACHING THEM about Himself and His ways first and foremost.
What was Paul doing for 20 odd years in Synagogues everywhere and the school of Tyrannus and every place everywhere he went?
TEACHING and persuading that Jesus is the Christ.
What was one of the FIRST THINGS (probably third) the risen Christ does? Can you guess?
TEACHING!
Luk 24:25
Then he said unto them, O fools, and slow of heart to believe all that the prophets have spoken:
Luk 24:26
Ought not Christ to have suffered these things, and to enter into his glory?
Luk 24:27
And beginning at Moses and all the prophets,
he expounded unto them in all the scriptures the things concerning himself.

This infantile attitude of despising/denying/avoiding teaching and teachers and ignoring the responsibility (due to laziness, heedlessness and irresponsibility) to rightly divide the truth is great folly IMO.
Time for everybody to grow up and get past group hugs and pablum and get out there and LEARN and TEACH and PREACH
thereby fulfilling the Great Commission.
Mat 28:18
And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth.
Mat 28:19
Go ye therefore, and
teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
Mat 28:20
Teaching them to
observe all things (DOCTRINE) whatsoever I have commanded you: and, lo, I am with you alway,
even unto the end of the world. Amen.
