I don’t think wedding cake-making for a gay couple is an absolute sin. A lot of people have stepped forward saying they will not make such a cake for such a couple - presumably because the cake makers would seem to send a message they do not want to send.
I’m torn, frankly, because both sides have made big stink about it. I don’t remember who started it, though I think it was the Christians. I think, for some Christians, it would be cooperation in mortal sin, or at least it would feel to be such to them. For others - not necessarily liberals - it would only be remotely related to a wedding.
What about Catholics? Well, we cannot cooperate in mortal sin, nor encourage it. The question is: is this cooperation or encouragement of mortal sin? The answer is, yes, to some degree.** How far a degree**, though - because not all degrees of involvement of sin are mortal or forbidden.
This article helped me determine my analysis here:
Degrees of Cooperation with Evil
Well,** is making a cake immediate material cooperation?** No; you’d really have to be the couple claiming to get married to be doing that.
Mediate material cooperation - assisting the act in some way? I think that would better describe, not even attending the wedding, but just baking a cake. So it might be morally neutral, although it might assist in an evil. Principle of double effect applies.
So we must then ask:
is this mediate cooperation remote, or proximate? This might be debated. After all, a wedding cake is part of the paraphernalia of a wedding. But it doesn’t seem to be used in the wedding itself, so much as the after-parties. It could very well be considered** remote mediate material cooperation.**
If we consider it remote rather than proximate, the next question is:** is baking a cake essential or non-essential to the evil action?** That should be** perfectly clear:** it’s unnecessary. They could still decide to get “married” even if no one in the world would bake a cake for them. Only takes a judge and some words. So denying a cake isn’t exactly a potent move.
There is good reason to believe baking a cake for a gay couple’s so-called “wedding” is morally permissible by a Catholic baker. The only question is whether such a service would be proximate or remote. Depending on how one looks at it - wedding cakes
are, after all, a conventional, traditional part of celebrating a wedding in our culture - it may, or may not be an occasion of sin to a man’s conscience.
Upon thinking about it, I don’t think it would be for me, if I made a living as a baker.
