My office aide was watching segments of the Today Show recently. The Catholic church has recently "lightened up" on its stance regarding unbaptized babies and limbo. I realize that limbo is not official church doctrine. What was funny to me, though not shocking at all, was that an official from the Catholic Church went on national TV and said that the Pope had asked their committee to re-examine the issue and put a more "positive spin" on it. The fact that any church changes positions on an issue or theological interpretation is not shocking. Most of my Catholic friends said "Don't you think we KNOW the church shifts on issues?" Of course! But now they're publicly admitting it on national TV.
In short, it's okay for the church to change it's mind. But not on the whole gay thing, of course. ;)
