I think I’ll pass on receiving Biblical instruction from any member of a religion that does not acknowledge that all Scripture is God breathed, but rather places more emphasis on it’s man-made traditions and rituals.
Where does it say that the prophets spoke of man made traditions?
They spoke the Word of God as warnings to the people of their day.
You certainly would not be referring the Last Supper and the Institution of the Holy Eucharist as man-made, would you? For the Holy Eucharist, as recorded in scripture, was instituted by Christ himself.
