How can the Catholic Church teach that we need Tradition as well as Scripture when the Bible says that Scripture is sufficient as a rule of faith and for making a man “complete”?

In this episode of Catholic Answers Focus, I chat with Cy Kellet about how I answer these questions in my book Meeting the Protestant Challenge.
