"One cannot believe in Jesus Christ without sharing in his Spirit. It is the Holy Spirit who reveals to men who Jesus is. For "no one can say "Jesus is Lord", except by the Holy Spirit", who "searches everything, even the depths of God. No one comprehends the thoughts of God, except the Spirit of God." Only God knows God completely: we believe in the Holy Spirit because he is God." (Catechism of the Catholic Church, 152)

These are contrasted with the works of the flesh in Galatians 5:19-21.
