The Holy Spirit descends upon Jesus in the form of a dove. The first Christians experience the Holy Spirit as a healing ointment, living water, a raging storm, or a flaming fire. Jesus Christ himself speaks about the Counselor, Comforter, Teacher, and Spirit of Truth. In the sacraments of the Church, the Holy Spirit is bestowed through the imposition of hands and anointing with oil. [691-193]
The peace that God established in his covenant with mankind after the flood was indicated to Noah through the appearance of a dove. Pagan antiquity, too, considered the dove to be a symbol of love. And so the early Christians understood immediately why the Holy Spirit, the love of God in person, came down in the form of a dove when Jesus allowed himself to be baptized in the Jordan. Today the dove is recognized worldwide as the sign of peace and as one of the great symbols for the reconciliation of man with God (cf. Gen 8:10-11)
