To begin with, it is certain that the declaration that there is no salvation outside the Church is not aimed at individual non-Catholics, at any persons as persons, but at non- Catholic churches and communions, in so far as they are non-Catholic communions. Its purpose is to formulate positively the truth that there is but one Body of Christ and therefore but one Church which possesses and imparts the grace of Christ in its fullness. Stated otherwise the declaration would run: Every separated church which sets itself up against the original Church of Christ stands outside the communion of Christ’s grace. It cannot be a mediator of salvation. So far as it is a separate and antagonistic church, it is essentially unfruitful as regards the supernatural life. So that that spiritual unfruitfulness which is predicated in the doctrine is not to be affirmed of the individual non-Catholic, but primarily of non-Catholic communions as such. By that which constitutes their separateness and differentiates them in faith and worship from the Catholic Church, they are able to awaken no supernatural life. Therefore, in so far as they are un-Catholic and anti-Catholic, that is to say in regard to their distinct character, they are not able to claim the honorable title of a “mother” church.
