Anything that supports the canon would be treated with respect, but not included with the inspired writings. At least not by Protestants, who don't accept the Apocrypha as inspired although the Catholics do. Some of the Apocrypha add interesting historical information that is accepted, but some of it also embellishes scripture stories too fantasically to be accepted.
The gnostic gospels, however, oppose the canon, have nothing to do with it.
I think Codegate put forward what seems to be a plausible sequence of events. In the above case the Church (at least many denominations) may well accept the Gospel, but it would not be added to the Holy Bible, but as supplementary reading material as it were.
This would be to treat it like the Apocrypha, but since it teaches something that contradicts scripture it will not be accepted by any orthodox church.
