An online acquaintance of mine had posted a translation of a snippet from Prof. Fr. Streckfuß in a document titled "The Preparation of the Sermon". He writes:
On a related note, another online acquaintance writing in response related the fact that his homiletics professor, a former district president, kept a set of crutches on his wall for students who required a manuscript to preach. Fritz in his pastoral theology assumes that the pastor memorizes his sermon (p.99), so he never mentions the alternative.
I'm of the opinion that a man who can preach without a manuscript–and I mean, really preach, not just recite a sermon from memory–is truly the recipient of a double blessing from God. My first fieldwork supervisor in seminary could preach for 25 minutes without a manuscript, and he was a compelling Lutheran preacher. The Lord did not bless me in this way. He did, however, bless me with the ability to write the way I speak: in a generally clear, easy to understand manner. Nevertheless, when I get too far from my manuscript, I lose my train of thought. Does it make me a less-skilled preacher? Possibly? Is the use of a manuscript less than ideal? I'll cede the point. Should it be a reason for a congregation to avoid calling a certain pastor? That's up to the calling congregation, of course, though I'd have to wonder what other expectations they'd have of the man they'd eventually Call. Should a man aspiring to the pastoral office be belittled–treated as a pastoral cripple–by a homiletics professor, a mentor, other pastors, because he uses a manuscript? By no means.
Why do we bind the consciences of men who aspire to the preaching office with requirements beyond what Scripture demands? It is an already weighty load. Why do we call into question the ability of the Holy Spirit to adequately equip the men Called to be prophets of the Most High? The Lord of the harvest sends men into the field with a variety of gifts. These various gifts allow them to do a myriad of things, all of them in service to the Kingdom.
Those men whom the Lord calls, He equips as He chooses. Let the Spirit do His work unquestioned and unhindered; and let the men He has called serve as He has equipped them, whatever those tools may be.
