Cronos,
I wrote “every Christian” because the essence of a Christian is someone who has entrusted himself to the Gospel of Grace for salvation. There is no other path, no other Gospel, no other Savior who paid the full price of sin.
Any one who has not entrusted himself to this Gospel of Grace may belong to a Christian religion/denomination, but they are not a saint.
Luther was flawed. Of this we can be confident. Every man who walks the earth is also - except The Man.
Blessings to you.

And all orthodoxy has believed that from apostolic times.
Luther did not inaugurate a separation in that.
