1Cor 13:1-3
"If I speak in the tongues of men and of angels, but have not love, I am a noisy gong or a clanging cymbal. And if I have prophetic powers, and understand all mysteries and all knowledge, and if I have all faith, so as to remove mountains, but have not love, I am nothing."
Paul lists the gifts most valued by the Corinthians (tongues, prophecy, knowledge, faith, generosity, martyrdom) and declares that without love (agape) all are nothing. The sounding bronze (chalkos echon) was used in the pagan rituals of Corinth — gifts without love are pagan religiosity.
