Question:
Answer:
It is not redundant because as human beings we often need things spelled out for us. The early Church had to address this a few times:
What good is it, my brothers, if someone says he has faith but does not have works? Can that faith save him? If a brother or sister has nothing to wear and has no food for the day, and one of you says to them, “Go in peace, keep warm, and eat well,” but you do not give them the necessities of the body, what good is it? So also faith of itself, if it does not have works, is dead. (James 2:14-17)
If anyone says, “I love God,” but hates his brother, he is a liar; for whoever does not love a brother whom he has seen cannot love God whom he has not seen. (1 John 4:20)
In the modern world it is easy to attend Mass on Sundays and holy days of obligation and think that we have loved God. And, indeed, it is an act of love for God. However, we can fall into a trap thinking that that is all we need to do and pay little to no attention to our brothers and sisters. That is why Jesus ties love of God and love of neighbor together so closely. Jesus does not want us to fool ourselves into thinking that we can love God without loving our brothers and sisters.
