Here's some information on this Charles Martel character.
On this site, he signed a letter sent to legislators calling for the "freedom to marry". Note that his signature is followed by "Roman Catholic Lay Leader," a title he has no doubt given himself.

He is on the steering committee for "The Religious Coalition for the Freedom to Marry," a front group for the activist homosexual lobby.

And he's apparently the person the Boston media has started seeking out when they're trying to find a Catholic "leader" to speak in favor of gay marriage.

He is also mentioned in connection with The Jesuit Urban Center in Boston, which in this article (appearing in "Bondings" -- some sort of gay Catholic periodical), is listed as a place where "Sunday Mass draws hundreds of gay Catholics."

In short, the guy is a dangerous dissenter in that he is trying to appear to be a Catholic leader and speak as such. Perhaps we should write to the Cardinal about him?
The Jesuit Urban Center 'Surprise, surprise, surprise,' said Gomer to Andy.
Is this another offshoot of Boston College?
