Here is where I can’t participate. Sacred Tradition for Catholics is from teh point of origin in Scripture and is continued through the Church making the Churches interpretation as primary as the Scripture (thanks to the recent “infallability of the Pope”). Most Protestants believe that Scripture alone is primary, and that Sacred Tradition (this is for Protestants) = the decisions of the early Church (Apostles, Nicenet, etc. creeds and docrines). Sacred Tradition in the Protestant sense is still over-ruled by Scripture if it is found in error, but because it is Sacred Tradition, they were guided by the Holy Spirit (hopefully, or we’re all going to hell!) therefore we trust the doctrines of the Trinity, for example.
Minor differences, let’s not forget what we share in common, but I represent different views on Sacred Tradition.
