All doctrines and all biblical interpretations are traditions. The doctrine of the penal substitutionary atonement as the interpretation of Romans is a traditional interpretation. So tradition is not something imported from the outside without roots in the Bible or not subject to reform by biblical revelation. Tradition is not a rival to the Bible or an alternative to it.
