Which man (of God) is perfect?
... we have to ask the RCC -- what more is there??? What do Rome's variable traditions and rites and relics and wooden statues and "other Christs" and "co-redeemers" provide that Scripture does not?
We could aks the same thing about the scripture readings and gathering on Sundays in Protestant lecture halls, hymns, public prayers...etc.
You said it above, quoting St. Paul, that a man of God manifests himself perfectly unto all good works. No words are necessary. People will recognize God's goodness in such a person by his works, not by the ritualistic waving of hands in the air, not through bible readings, not through uniformed choirs singing man-made hymns, or baptismal ceremonies.
Why, speaking of traditions, Presbyterian churches did not allow any kind of instrumental music for a long time. I bet you, most Presbyterians never even think about their choirs as unnecessary, man-made tradition added to Protestant rituals.
Curious... why do you think choirs are “man made” additions to worship?
