In July 2010, I formally requested dispensation from my promises as a member of the Lay Fraternities of St. Dominic.
I'll characterize the reasons this way: While I think I was pretty solid on the theory, in practice I was a lousy Dominican, and I judged it better to not be a Dominican than to be a lousy one.
I haven't publicly mentioned this till now mostly because it's humiliating, but also because I don't want my own faults to reflect poorly on the Lay Fraternities. At this point, though, I'd say there's a greater risk that the virtues of the Lay Fraternities will reflect falsely on me.
So, while I stand behind all I've written about the Dominicans, what I've written about my own vocation to the Order is wrong.
