In fact the Archdiocese has been responsible for the development of lots of affordable housing on Washington St. and around eastern Mass. for decades; trouble is there's been little press about it....Hmmm, the Catholic Church doing really good things for the community? Nah....doesn't sell papers.
You're absolutely right, the business of the Church is to do good things for the community and they've done a wonderful job providing many services for the public at large. However, when priests and bishops and cardinals of the Church stray from that mission by committing crimes, and the Catholic Church covers up for them, they're gonna get as much press as the next organization. A teacher who's taught for 25 stellar years, then molests one of his/her charges, is gonna get some pretty tough press, a ruined reputation, and possibly jail-time as they should. Should be no different for the Church.
