There is no scriptural information on a LOT of stuff that the Church tells it's members they HAVE to do.
They are purely conjecture; too; but I'm sure you have a list of them handy.
Yea .... are Nicene/Apostolic/Athenasian creeds conjecture or biblical?
If they are biblical ..... Prove it! If not .... Matt 7:5
“Thou hypocrite, first cast out the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother’s eye”
