As I read this here was his response:
Instead, a diocesan spokeswoman directed CNSNews.com to a statement on the diocesan website where the bishop writes, “We have never wavered from our traditional Catholic teachings.”
So I guess he could read from the Catechism or Romans but it seems sufficient to me to refer the questioner to the sources.
If the bishop truly believed in traditional Catholic teaching, why did he fire a teacher for posting those same teachings on her personal Facebook account?
