Jesus Christ, after his Resurrection together with the Father sent the Holy Spirit in order that he might accomplish from within the work of salvation and that he might animate his disciples to continue the mission to the whole world. He was the first and supreme evangelizer. He proclaimed the Kingdom of God,^{66Cf. Mk 1:15 and parallels. RM 12-20; CCC 541-560.} as the urgent and definitive intervention of God in history, and defined this proclamation "the Gospel", that is, the Good News. To this Gospel, Jesus devoted his entire earthly life: he made known the joy of belonging to the Kingdom,^{67Cf. Mt 5:3-12.} its demands, its magna carta,^{68Cf. Mt 5,1-7,29.} the mysteries which it embraces,^{69Cf. Mt 13:11.} the life of fraternal charity of those who enter it ^{70Cf. Mt 18:1-35.} and its future fulfilment.^{71Cf. Mt 24:1-25,46.}
