"you begin to understand it [the impact of one's baptism] in the encounter with a living Christian companionship" (Julián Carrón).
"Baptism is the sacrament of faith. But faith needs the community of believers. It is only within the faith of the Church that each of the faithful can believe. The faith required for Baptism is not a perfect and mature faith, but a beginning that is called to develop" (CCC 1253)."Catechesis aims at coming to know Jesus concretely [....] catechetical instruction also includes a pilgrim fellowship, a gradual familiarization with the new life-style [or form of life] of Christianity" (Ratzinger, Gospel, Catechesis, Catechism, 56-57).
