You might call it the "doctrine of the unevangelized." Sunday morning, the sermon broached this by speaking about "exclusivism."
In our postmodern, DEI culture, "inclusion" pretty much requires a pluralism. Pluralism is the belief that all roads lead to heaven. Except for the very few that might be labeled evil (a "Hitler" type), people are basically good and whatever they believe can certainly get them to heaven. It does beg the question, "If there are a multitude of beliefs that can get to heaven, does this require that there are a multitude of heavens?" Mine is going to have a hammock that is ever swinging, on a warm sunny day, with a nice breeze, and an ever-cold, ever-full glass of iced tea. Oh, and some occasional meals and snacks brought to me. All roads lead to all heavens.
Inclusivism sounds like Christian teaching at first glance. Inclusivists believe that Jesus is the only Savior. They believe there is no other name given to humans whereby we must be saved (Acts 4:12). They even might agree that no one can get to the Father except through Jesus Christ. Yet, they adhere to a belief that a person does not need to explicitly know about and believe in Jesus to be saved by Jesus. People are saved by Jesus even if they don't know that they are saved by Jesus!
Inclusivism, at the end of the day, is really just pluralism dressed up like Christianity. We serve a merciful God who does desire that all be saved (1 Tim. 2:4) but He is a just judge and requires individual repentance to and belief in Jesus Christ to be saved. May we not get duped by the politics of inclusivity and lose our witness.
God has given us testimony! Mankind's testimony of Jesus (the disciples saw him, heard him, and touched him). God's divine testimony of Jesus: the Father affirmed Jesus at the baptism (the water), He shook the earth cataclysmically at the cross (the blood), and His Spirit remains a witness to us today that Jesus Christ is God's only begotten son, our Lord and Savior! Let's join in that testimony and share it with others so that they might excitedly bow to Jesus as their Lord and Savior.
