171. What is the meaning of the affirmation “Outside the Church there is no salvation”?

846-848
This means that all salvation comes from Christ, the Head, through the Church which is his body. Hence they cannot be saved who, knowing the Church as founded by Christ and necessary for salvation, would refuse to enter her or remain in her. At the same time, thanks to Christ and to his Church, those who through no fault of their own do not know the Gospel of Christ and his Church but sincerely seek God and, moved by grace, try to do his will as it is known through the dictates of conscience can attain eternal salvation.

262. Is it possible to be saved without Baptism?

1258-1261
1281-1283
Since Christ died for the salvation of all, those can be saved without Baptism who die for the faith (Baptism of blood). Catechumens and all those who, even without knowing Christ and the Church, still (under the impulse of grace) sincerely seek God and strive to do his will can also be saved without Baptism (Baptism of desire). The Church in her liturgy entrusts children who die without Baptism to the mercy of God.
