"This past week we implemented a policy that has been the most difficult decision of my life," writes Father Bill Breslin of Boulder's Sacred Heart of Jesus Catholic School in a blog post titled "Moses and the Burning Bush ." Breslin is referring to his decision to ban a student whose parents are lesbians, adding he "chose to protect the faith over doing what would have looked like the loving thing to do.... Our school is a Catholic school, and our teaching on the sanctity of marriage is as clear as a bell." A small group of protesters gathered outside the church on Sunday, including Kira Hall, who held a sign that read, "God loves all people." Another protester, Colleen Scanlan Lyons, whose daughter attends the school, told 9News , "I've had 16 years of Catholic education, and this just reached the core of my being as completely wrong and against the teachings of Jesus." Breslin has made it clear that he's not budging on the issue, but gay advocates aren't giving up their fight. Boulder Pride is investigating to see what can be done to help the family, as well as talking about discrimination "in our own backyard," writes the Daily Camera .
