Rhode Island has legalized same-sex marriage and Archbishop of Providence has issued a letter:
The letter is an excellent example of why our bishops are so ineffectual in slowing the march to same-sex marriage. Here is a sample paragraph:
And because “same-sex marriages” are clearly contrary to God’s plan for the human family, and therefore objectively sinful, Catholics should examine their consciences very carefully before deciding whether or not to endorse same-sex relationships or attend same-sex ceremonies, realizing that to do so might harm their relationship with God and cause significant scandal to others.
After stating that ssm's are objectively sinful, he tells Catholics to consult their consciences and that supporting ssm's MIGHT (!!!) harm their relationship with God. Well then I guess it's 50/50.
