Those who listen to my podcast are probably familiar with Leroy Huizenga (go here and here). Leroy is a brilliant New Testament scholar as well as Chair of the Department of Theology and Director of the Christian Leadership Center at the University of Mary in Bismarck, N.D.
Among other notable items in his curriculum vitae, he earned a M.Div. from Princeton Theological Seminary and a Ph.D. in New Testament from Duke University.
After teaching at Wheaton College for five years, Leroy returned to the Catholic faith he was born into when, at the Easter Vigil of 2011, he was reconciled with the Catholic Church.
And, on top of all that, he has a great blog.
Among other things, be sure to check out this post in which Leroy reproduces a letter of St. Francis of Assisi to his brothers on the topic of liturgical propriety. Fascinating stuff!
