. This doctrine of Predestination comprises within it neither the whole nor any part of the Gospel. For, according to the tenor of the discourses delivered by John and Christ, as they are described to us by the Evangelist, and according to the doctrine of the Apostles and Christ after his ascension, the Gospel consists partly of an injunction to repent and believe, and partly of a promise to bestow forgiveness of sins, the grace of the Spirit, and life eternal. But this Predestination belongs neither to the injunction to repent and believe, nor to the annexed promise. Nay, this doctrine does not even teach what kind of men in general God has predestinated, which is properly the doctrine of the Gospel; but it embraces within itself a certain mystery, which is known only to God, who is the Predestinater, and in which mystery are comprehended what particular persons and how many he has decreed to save and to condemn. From these premises I draw a further conclusion, that this doctrine of Predestination is not necessary to salvation, either as an object of knowledge, belief, hope, or performance. A Confession to this effect has been made by a certain learned man, in the theses which he has proposed for discussion on this subject, in the following words: "Wherefore the gospel cannot be simply termed the book or the revelation of Predestination, but only in a relative sense. Because it does not absolutely denote either the matter of the number or the form; that is, it neither declares how many persons in particular, nor (with a few exceptions,) who they are, but only the description of them in general, whom God has predestinated."
Schuller does not preach the lostness, repentance, forgiveness, salvation.... Therefore, he is no Arminian.
That knocks him out of the Protestant camp all together.
He demonstrates the natural progression of Arminianism.
