There are great differences in the purity of confessions and churches, and we must aim and strive for the purest. Those, therefore, who have come to believe that the Protestant church is better than the Roman Catholic Church and that the Reformed church is purer than the Lutheran, the Remonstrant, or the Baptist, must, without condemning their own church as false, leave it and join the other. And to stay in one's own church despite much impurity in doctrine and life is our duty as long as it does not prevent us from being faithful to our own confession and does not force us, even indirectly, to obey humans more than God. For a church that pressured its members to do that would, at that very moment and to the extent it did that, reveal itself to the conscience of its members as a false church, which accorded itself and its ordinances more power and authority than the Word of God.
