Proposals for a Correct Reading of the Second Vatican Council – Bishop Athanasius Schneider 

Such a proclamation [of the Gospel to all non-believers] must be explicit: that is, faith in Jesus Christ, to which one arrives by the grace of conversion and repentance. Therefore there is no room for a theory and a practice of so-called “anonymous Christianity”, there is no acceptance of alternative ways of salvation other than the way of Christ: Christ is the one Mediator between God and men. This is what the Council teaches in the Dogmatic Constitution Lumen Gentium, saying: 

The Church, now sojourning on earth as an exile, is necessary for salvation. Christ, present to us in His Body, which is the Church, is the one Mediator and the unique way of salvation. (n. 14) 

In paragraph n. 8 of the same Dogmatic Constitution, the Council says: “Unicus Mediator Christus” (see also ibid., n. 28). Human beings who are saved in eternity are saved by their acceptance of the merits of the one Mediator, Jesus Christ, in their earthly life (ibid., n. 49). The Second Vatican Council teaches, presenting the following quotation from the Council of Trent: “per Filium eius Iesum Christum, Dominum nostrum, qui solus noster Redemptor et Salvator est” (ibid., n. 50). In the Declaration on Religious Liberty the Council teaches that every man is redeemed by Christ the Savior and is called to Divine sonship, which can be received only by means of the grace of faith (Dignitatis humanae, n. 10).
