XXVIII. In this belief we declare that, properly speaking, there can be no Church where the Word of God is not received, nor profession made of subjection to it, nor use of the sacraments. Therefore we condemn the papal assemblies, as the pure Word of God is banished from them, their sacraments are corrupted, or falsified, or destroyed, and all superstitions and idolatries are in them. We hold, then, that all who take part in these acts, and commune in that Church, separate and cut themselves off from the body of Christ Nevertheless, as some trace of the Church is left in the papacy, and the virtue and substance of baptism remain, and as the efficacy of baptism does not depend upon the person who administers it, we confess that those baptized in it do not need a second baptism. But, on account of its corruptions, we can not present children to be baptized in it without incurring pollution.
