Church theology demands that we accept that:
- All things were made by God.
- The human soul is specially and immediately created by God.
- Adam was a very real human, and the first “true man” in that he was the first homonid to have a human soul.
- Eve was a very real human, and the first “true woman”, and Adam’s wife.
- All true humans claim descent from this original pair; no one is alive today who can not trace their lineage back to them.
These are
the dogmas we must accept as Catholics. Any opinion which embraces these dogmas is orthodox, meaning both creationism and evolution can be orthodox. You’ll notice that there is no dogma about how the human body was formed, and that’s where evolution and creationism are free to disagree. What we are not free to do is deny the orthodoxy of the opposing viewpoint, though we are free to debate it. So when we say that you’re not free to oppose it, we’re saying that you’re not free to oppose its presence in the Church.
A similar example would be the use of leavened or unleavened bread in the Eucharist. There are Eastern Catholics who use leavened bread, and they have theological reasons for their preference. We, as Western Catholics, are free to disagree with their preference, and possibly even debate why one is better than the other, but we are NOT permitted to oppose the use of leavened bread as unorthodox; the Church has already spoken on what constitutes the proper bread for Transubtantiation to occur, and both leavened and unleavened bread fall within that definition.
