This is what Jesus says are the 2 greatest commandments

One of the scribes who had come up and heard them disputing, knowing that he had answered them in a fine way, asked him: “Which commandment is first of all?” Jesus answered: “The first is, ‘Hear, O Israel, Jehovah our God is one Jehovah, and you must love Jehovah your God with your whole heart and with your whole soul and with your whole mind and with your whole strength. The second is this, ‘You must love your neighbor as yourself. There is no other commandment greater than these. The scribe said to him: “Teacher, you spoke well, in line with truth, ‘He is One, and there is no other besides him’; and to love him with one’s whole heart, with one’s whole understanding, and with one’s whole strength and to love one’s neighbor as oneself is worth far more than all the whole burnt offerings and sacrifices. At this Jesus, discerning that he had answered intelligently, said to him: “You are not far from the Kingdom of God.” But no one had the courage to question him anymore.

 

Yep.
