Friend, there is only one Gospel. All of the groupings you just mentioned are in agreement on this Gospel, which can be boiled down to this: All humans sin and fall short of God's glory The wages of sin is death (after physical death, eternal separation from God) The gift of God's undeserved, unearnable grace is offered to all who accept it by faith in Jesus Christ the Redeemer It is the easiest thing to do, and yet it is the hardest thing to do.
There certainly are several unique people on this forum, but I never expected to encounter a self-described agnostic "trickster" who derives pleasure from "stirring the pot" at his local CoE parish. At least he is transparent with his intentions.
