According to the Catholic conception of justification the redemptive function of the Church does not consist only in bringing the Kingdom of God to man, but also in bringing man to the Kingdom of God, i.e. in educating his moral will, by preaching and discipline, for Christ and His grace, and in establishing him ever more and more firmly in this grace. We have to consider therefore, besides that pastoral activity of the Church which is sacramental and brings grace to men, her educative activity also, that is to say her earnest endeavor that “the tree planted by the running waters shall bring forth its fruit in due season and that its leaf shall not fall off (Ps. i, 3).
