Preaching and Teaching Acceptance and Love
This makes me want to cry. If it were to follow its own logic -- that they're simply following the teachings of the Catholic church -- the archdiocese should start expelling children of parents who have had abortions, or who use birth control. But why stop there? Expel children of parents who are who are divorced, who support euthanasia, and who have had sex outside of marriage. Expel children of parents who have practiced anything that "goes against" church teachings.
If God is love, and if the church's intent is to lead people to Christ, it must accept ALL PEOPLE.
"Jesus said, 'Let the little children come to me, and do not hinder them, for the kingdom of heaven belongs to such as these.'" -- Matthew 19:14 (New International Version)
