[TBC: Former evangelical Francis Beckwith discussed his conversion to Catholicism and noted some things he felt he could take with him from evangelicalism as he entered the Catholic church.]
Former ETS president speaks about what he takes from evangelicalism back to the Roman Catholic Church [Excerpts]
Look, you're not going to come up with the Nicene Creed by just picking up the Bible. Does the Bible contribute to our understanding? Absolutely it does; the Nicene Creed is consistent with Scripture. But you needed a church that had a self-understanding in order to articulate that in any clear way. I am not saying that necessarily means that you have to be a Catholic. But we have to understand that the Reformation only makes sense against the backdrop of a tradition that was already there. Calvin and Luther did not go back and re-write Nicea. They took it for granted. There's nothing wrong with conceding that and celebrating it and reading those authors.
Looking at tradition would also help evangelicals learn about Christian liturgical traditions, like Eastern Orthodoxy and Catholicism, that evangelicals reject because they say liturgy is unbiblical. When did these practices come to be? It turns out many of them came to be very early on in church history when people were close historically to the apostles themselves. There must be something to these practices that the early Christians thought was perfectly consistent with what they had received from the apostles (Neff, Q&A Francis Beckwith, Christianity Today Online, 5/09/2007).
[Preconceptions drive the conclusions of Beckwith. Concerning very early church traditions, Paul specifically warned the Church about such traditions. “Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers, to feed the church of God, which he hath purchased with his own blood. For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock. Also of your own selves shall men arise, speaking perverse things, to draw away disciples after them“ (Acts:20:28-30).]
