A lot of evangelicals are swimming these days. They're slipping on their metaphorical fins and masks and churning their way across bodies of water to emerge on the other shore as members of a different faith community. Those that move from evangelicalism to Roman Catholicism are said to swim the Tiber; those that become Orthodox swim the Bosporus.
Reasons for their aquatic activities vary. Some like the art and architecture associated with the ancient faiths. Some like the ceremonial aspects–the liturgies, the veneration of icons, the Eucharist. Some like the history that oozes from Catholicism and Orthodoxy, a history that travels through great saints of yesteryear–through Augustine, Ambrose, Chrysostom, and Gregory of Nazianzus–but goes largely forgotten in contemporary evangelicalism.
