On what authority do you proclaim that Holy Roman Catholic Church is not the truth on matters of faith?
Your personal opinion, Luther’s personal opinion or someone else’s opinion?
Matthew 16:
18k And so I say to you, you are Peter, and upon this rock I will build my church,* and the gates of the netherworld shall not prevail against it. 19l I will give you the keys to the kingdom of heaven.* Whatever you bind on earth shall be bound in heaven; and whatever you loose on earth shall be loosed in heaven.
