Peter did not wear a funny hat, my denomination is Christian
you know this how???
That Peter did not wear a funny hat certainly has the weight of probability on its side, but cannot be proven, and far less can it be proven, among other things from Scriptures showing the life of the NT church,
that NT pastors were distinctively titled "hierus=priests,"
as their man function was a uniquely sacrificial one in offering the Eucharist as an atonement for sin,
by which souls obtained spiritual life,
and prayed to saints,
and who looked to a supreme exalted infallible pope in Rome
whose church possessed assured perpetual infallibility as the instruments and stewards of Scripture,
which infallibility is essential to know which writings are of God.
