With respect, those who said that the Lutherans have three sacraments are mistaken. Baptism, the Eucharist, and Absolution are certainly sacraments, but the thing about the Lutheran thinking on the number of sacraments is that we do not insist dogmatically on a particular number of sacraments. This is because the very definition of a sacrament can vary, and in fact, the Book of Concord is open to seeing Ordination as a sacrament, same for Marriage. For that matter, the Lutheran Confessions are not opposed to any of the classic seven being termed sacraments per se. Marriage is highly valued, for example, but it is not vital to term it a sacrament. Some think Lutheranism has a low view of Ordination, yet without it, we wouldn’t have presbyters. The difference between Lutheranism & Roman Catholicism on the matter of sacraments, what they are, what they give, etc, cannot be done justice in a paragraph, but is in many ways smaller than Catholic apologists often imply (the difference is also smaller than many modern Lutherans have been led to think). Part of the difference is in our (traditional Lutheranism’s) distaste for confining matters to Thomistic categories.
