Roman Catholics have emphasized the juridical or administrative fruits of baptism: forgiveness of sin, membership in a group. Maybe not so much the apostolic effect, that people are then obliged to enter into a corps of disciples and missionaries:
349. The call of Jesus in the Spirit and the Church’s proclamation always appeal to our trusting acceptance by faith. “He who believes in me has eternal life.” Baptism does not merely purify from sins. It causes those who are baptized to be reborn, conferring on them the new life in Christ, who incorporates them into the community of disciples and missionaries of Christ, into the Church, and makes them children of God; it enables them to recognize Christ as Firstborn and Head of all humankind. Being brothers and sisters means living fraternally and being ever alert to the needs of the weakest.
These days, it is a distinct minority who adopt the stance of disciple. Members of that minority have a certain obligation to their less active companions.
