WHY SCRIPTURE AND TRADITION?

Formation Claim

Catholics hold that Scripture and apostolic Tradition transmit the one deposit of faith, served by the bishops' teaching office in communion with the pope.

Historical context

Catholic teaching distinguishes apostolic Tradition from local customs and describes Scripture and Tradition as closely joined in transmitting revelation. The teaching office serves and interprets that deposit; its precise authority is a developed ecclesial doctrine.

Avoid overclaiming

Catholic doctrine does not place the Magisterium above God's word: Dei Verbum says it serves that word. Nor does 'Tradition' mean that every historical custom is an unchangeable apostolic doctrine.

Strongest alternative reading

Orthodox Christians also locate Scripture within received Tradition, but dispute the Catholic account of a universal papal teaching office. Classical Protestants distinguish apostolic oral teaching from later tradition and treat Scripture as the final test of councils and confessions.

Basil defends written teaching and received unwritten practices while explaining his doxology concerning the Spirit.

Basil's examples include the sign of the cross, eastward prayer, and baptismal and eucharistic practices. These are his claims about received apostolic practice, not independent first-century documentation of each example.
