Since its inception Gottesdienst has included the title Father for clergymen and the term Mass for, well, for the Mass, as part of its style guide. This, along with the chasubles, chanting, and genuflecting will sometimes provoke the charge of "too Catholic" or "weirdos" or even things less complimentary. In the past some well meanings folks have suggested that we just drop all the Catholic lingo: we'd get way more traction in our goals of restoring Lutheran worship if we just referred to clergymen as Pastor and the Mass as the Divine Service.
And, likewise, [ministers] are called "fathers" (2 Kings 6:21). This title is repeated in the New Testament (I Cor. 4:15; Gal. 4:19) not merely for the sake of honor but also because through the Word they beget spiritual children to God - instrumentally, that is; and in this sense and respect they are said to save both themselves and their hearers (I Tim. 4:16).
Besides these there are yet spiritual fathers; not like those in the Papacy, who have indeed had themselves called thus, but have performed no function of the paternal office. For those only are called spiritual fathers who govern and guide us by the Word of God;159] as St. Paul boasts his fatherhood 1 Cor. 4:15, where he says: In Christ Jesus I have begotten you through the Gospel. Now, 160] since they are fathers they are entitled to their honor, even above all others. But here it is bestowed least; for the way which the world knows for honoring them is to drive them out of the country and to grudge them a piece of bread, and, in short, they must be (as says St. Paul, 1 Cor. 4:13) as the filth of the world and everybody's refuse and footrag.
