"God and Father of all who believe in you, you promised Abraham that he will become the father of all nations, and through the death and resurrection of Jesus Christ you fulfill that promise. Everywhere throughout the world you increase your chosen people. May we respond to your call by joyfully accepting your invitation to the new life of grace ….." (Prayer at the Mass of Easter Vigil)
At the Easter Vigil everywhere in the world, new members are added to the Church through the baptism of catechumens and the welcoming of candidates into the Church.
Jesus Christ is the means through which the promise to Abraham is fulfilled.
