I don’t believe that any denomination has a monopoly on the truth. And to say that any does is wrong.
I believe we will see Baptists, Catholics, Pentecostals, Lutherans, (insert Christian denomination here).
It’s through the Blood of Christ and nothing else. As far as needing to go through a priest for the forgiveness of our sins, “No man comes to the Father, except through the Son”. No one else is needed. Praise God for that!
There are no non-Christians in heaven?
