l'abbé Antoine Galland, membre d'une congrégation conservatrice, la communauté Saint Martin, implantée dans le Var depuis une vingtaine d'annéesI take it this means that he is a member of the conservative "Community of St. Martin" which has been in the province of Var for about 20 years.
I'm not familiar with this group, and a quick google search did not turn up any information.
Is this it?
