I guess I'm late. I am just hearing about this situation where the son of a lesbian couple is having his admission into a Catholic school rescinded, because his parents are lesbians. I think that the church is well within its rights to do exactly what it did, and I hope that the ladies don't try to force the church to accept their son.
I think that the hypocrisy of the church's position should be highlighted regularly. Apparently, there are children attending that school who have divorced parents. Why have they not been asked to leave the school? I would think that breaking the sacrament of marriage would be high on the "no-no" list. But, I guess not.
I also think that someone in Massachusetts needs to see exactly how much public money finds its way into that school, and then demand that the school return every penny. If there is public funding going to the school in some way, then the school needs to return that public money and treat all who apply equally, regardless of the status of the parents. But, if there is no public money involved, then I would be the first to say that the church has every right to determine the individuals with whom it wants to associate.
