If you'd like to go through a fairly in-depth study of St. Paul's Epistle to St. Titus, you'll find it here. There are two sessions of one hour each.
Also at the same site are podcasts of our study of St. Mark's Gospel, and the Epistle to the Hebrews.
I am now teaching a series on St. Paul's two epistles to the Thessalonians. We meet on Wednesday evenings at 6:45 p.m. When the series is finished I'll post podcasts of the sessions.
