I just discovered the first two articles of a continuing series on the Sacrament of Baptism written by Mark Shea, another recent convert to the Catholic Church. They provide a nice counterpoint to John Piper's sermons, which I am in the middle of critiquing. Further, Shea writes with Piper's perspective in mind, since it is the perspective he once held as an Evangelical. Shea's essays are worth reading, and I'll update this post as further installments are published.
