Such terms as the above, as with "father," "vicar," and "primate," are very, very odd, in a church which would recognize the total primacy of Jesus Christ (THE image of the Invisible God) as the other current thread asserts.
I don't choose to beat up anyone for his religious particulars (and am not a fan some of the Reformers doctrines that also draw outside the lines) but I do choose to accept the truth from God's perspective, no one "getting in His/my light," whether it pleases any mere man, or not.
And you do know there isn't some group somewhere in the Vatican with "Magisterium" on the office door.
How do you feel about "pastor"?
