..."unless properly called" (Latin -...nisi rite vocatus) or "...without a proper (public) call" (German -...ohn ordentlichen Beruf refers to the entire process of sustaining the Church's ministry (the initial personal call, the public authorization [ordination], and the local, congregation service, however that is determined). It does not refer to our modern congregational call because the Lutherans did not do that until they came to America. The Roman Catholics approved this article (XIV) of the Augsburg Confession as do I, most certainly.
