Catholics need to follow Jesus. Not a Jesus that they have invented for themselves, but the real Jesus.
That means not supporting abortion, artificial contraception , embryonic stem cell research, gay marriage, euthanasia, and other things that the Church has condemned!
One would think that what I am saying would be a given. Yet, liberals insist on proclaiming a Jesus that did not exist in the Gospels. For example, you should see the comments I got when I did a post on this at the Catholic Catechism Dialogue Blog.
The Church has it's authority from Christ. When you disobey the Church, you disobey Christ!
