With all due respects to our Lutheran brethren, I think the Missouri Synod isn't a compromise at all. As much as it condemns synergism and man's "cooperation" in any form, it nevertheless argues against monergism and, in particularly, universal atonement and irresistible grace.
The statement that bothers me the most of the Missouri Synod is this:
14. As to the question why not all men are converted and saved, seeing that God's grace is universal and all men are equally and utterly corrupt, we confess that we cannot answer it. From Scripture we know only this: A man owes his conversion and salvation, not to any lesser guilt or better conduct on his part, but solely to the grace of God. But any man's non-conversion is due to himself alone; it is the result of his obstinate resistance against the converting operation of the Holy Ghost. Hos. 13:9.
This is the exact same problem that SD has and the root of the cause. No synergist can say WHY someone is saved and someone else is past by. The Missouri Synod admits that they have "no answers" to the "mystery" except they know that Calvin can't be right. That's why I state there is not more that a dime's worth of difference between some Protestants and Catholics. I'd like to know if the Missouri Synod can't explain it how do they know Calvin was wrong? Please also note that man’s salvation is due to God’s grace but man’s non-conversion is due to “himself”. That of course begs the question doesn’t man REALLY do something.
To a monergistic person the answer is simple contrary to what some keeps telling me is impossible to understand; God saves some, He does not save others. To simply reject an argument (one that is the ONLY plausible argument) as the Missouri Synod does and not have any alternative is not logical. While the Missouri Synod seemingly denounces synergism, it is nonetheless synergistic.
This isn't a shade of gray issue but a black and white. Either salvation is synergistic that man does something (if nothing else reject) or salvation is monergistic that God does it all.
