Catechesis: Church Practices

So the churches will not condemn one another because of differences in ceremonies when, in Christian liberty, one has less or more of them. This applies as long as they are otherwise agreed with one another in doctrine and all its articles, and also in the right use of the holy Sacraments. This fits with the well-known saying: “Disagreement in fasting does not destroy agreement in the faith.”—FC SD XI:31
