Martin Luther, "On Married Life," 1522: "I permit you to confirm as long as it is known that God has said nothing about it, and also knows nothing about it, and that what the bishops allege about it is false. They mock our God in saying that it is a sacrament of God when it is merely a human invention."
Council of Trent, "On Confirmation," 1547: "If people say that confirmation of the baptized is an idle ceremony and not rather a true and proper sacrament, or that once it was nothing other than a kind of catechizes by which those close to adolescence explained the reasoning of their faith before the assembly, let them be accursed."
