CCC 1269 Having become a member of the Church, the person baptized belongs no longer to himself, but to him who died and rose for us.1 From now on, he is called to be subject to others, to serve them in the communion of the Church, and to “obey and submit” to the Church’s leaders,2 holding them in respect and affection.3 Just as Baptism is the source of responsibilities and duties, the baptized person also enjoys rights within the Church: to receive the sacraments, to be nourished with the Word of God and to be sustained by the other spiritual helps of the Church.4

CCC 1270 “Reborn as sons of God, [the baptized] must profess before men the faith they have received from God through the Church” and participate in the apostolic and missionary activity of the People of God.5
