For laying aside the commandment of God,
ye hold the tradition of men,
Mark 7:8
".....in The Babylonian Captivity of the Church, Luther stated: “What is asserted without the Scriptures or proven revelation may be held as an opinion, but need not be believed.” Luther did not reject tradition outright. He respected the writings of the early church fathers, ..... and he considered universal statements of faith, such as the Nicene and Athanasian Creeds, binding on the church in his day.
But he maintained that
all creeds,
sayings of the fathers,
and decisions of church councils must be judged by,
never sit in judgment upon,
the “sure rule of God’s Word.”
