It is no longer strange to hear some pastor from here or there defecting to Rome or Constantinople.
Here is my theory why this thing happens. Well, if you believe people are already saved, they just have not believed it yet, you will defect too. Doctrine or what not won't matter, because if in the end, people are already declared righteous they just haven't believed it yet, what is the problem? It won't make a hill of beans if one moves to Rome or Constantinople, so they do move.
A few months ago, I sat under a lecture by a Lutheran theologian. I was just amazed how he spoke sweetly of Rome. I credit him for being composed at my questions, I challenged him why he hasn't converted yet! I really respect his gentlemanly way of answering my questions, but I was somewhat disappointed at his apparent naive romantic way of looking at Rome. I could have sworn he was a crypto-papist.
The more I read the Large Catechism, the more I am convinced Luther did not believe in this business - all are saved, they just have not believed it yet, or all are declared righteous, they just have not believed it yet. One time, one guy was trying to prove to me that God already was treating Abraham righteous because God was already speaking to him. I said Rom 4:3 was the time when he was declared righteous and not before, it was just water off duck's back.
In fact in the Large Catechism, Luther believed that those who do not believe the Gospel are under God's wrath - today, now!!!
We could have people sitting with us in our churches who could be denying the Gospel, i.e., those who do not trust the Gospel, and are then in God's wrath. In fact Luther referred to them as false Christians.
Here is what Luther said...
Apostle's Creed III
61] This, now, is the article which must ever be and remain in operation. For creation we have received; redemption, too, is finished But the Holy Ghost carries on His work without ceasing to the last day. And for that purpose He has appointed a congregation upon earth by which He speaks and does everything. 62] For He has not yet brought together all His Christian Church nor dispensed forgiveness. Therefore we believe in Him who through the Word daily brings us into the fellowship of this Christian Church, and through the same Word and the forgiveness of sins bestows, increases, and strengthens faith, in order that when He has accomplished it all, and we abide therein, and die to the world and to all evil, He may finally make us perfectly and forever holy; which now we expect in faith through the Word.---66] These articles of the Creed, therefore, divide and separate us Christians from all other people upon earth. For all outside of Christianity, whether heathen, Turks, Jews, or false Christians and hypocrites, although they believe in, and worship, only one true God, yet know not what His mind towards them is, and cannot expect any love or blessing from Him; therefore they abide in eternal wrath and damnation. For they have not the Lord Christ, and, besides, are not illumined and favored by any gifts of the Holy Ghost.
