The body of Christ is nothing without the head, who gives it life.
How can we love the Head without loving the body?
We love the body of Christ
1 John 4:20

Some context around the verse you're citing:
15Whoever confesses that Jesus is the Son of God, God abides in him, and he in God. 16We have come to know and have believed the love which God has for us. God is love, and the one who abides in love abides in God, and God abides in him. 17By this, love is perfected with us, so that we may have confidence in the day of judgment; because as He is, so also are we in this world. 18There is no fear in love; but perfect love casts out fear, because fear involves punishment, and the one who fears is not perfected in love. 19We love, because He first loved us. 20If someone says, “I love God,” and hates his brother, he is a liar; for the one who does not love his brother whom he has seen, cannot love God whom he has not seen. 21And this commandment we have from Him, that the one who loves God should love his brother also.
Doesn’t the RCC believe/teach that Mary is the Neck that joins the Body to the HEAD?
