Some traditions change but the Holy Tradition from which the Holy Scripture itself came, does not change. It is simply the deposit of faith delivered to the Church that did not make it into canonized writing.
The traditions that do not come from scripture are traditions of men.. most of them added after Constantine.
They are accepted on faith alone
Traditions like the "mass" the priesthood, the pope,statues, etc,
Sola Ecclesia Romanus
Only the Church of Rome is the Rule of Faith
