At this moment of cultural change, it is important to affirm the teaching of the Church, based on God’s word, that “homosexual acts are intrinsically disordered,” (Catechism of the Catholic Church, #2357) and always sinful. 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.It's not the first time that the hierarchy has called on people to shun their gay loved ones. There are numerous examples from Minnesota during their amendment battle last fall. And of course, punishments against those who would dare support gay couples, like denying Confirmation or Communion. It smells of desperation, given that the Roman Catholic laity are strong supporters of equality.
From Andrew Sullivan :
All they have is calling our orientation “intrinsically disordered” and our families “clearly contrary to God’s plan” in a way they would never use with respect to, say, civilly divorced Catholics or those using contraception.... Take the right to a stable home away, and you do not bring health, happiness and peace. You bring sickness, depression and pain. And the reason some in the hierarchy still do not see this is because they cannot yet see gay people as human beings, with dignity. And that is what is “intrinsically disordered” from a Christian point of view.
