Hey fix, Ill respond to you first as your question is faster!
By practical, I mean not requiring any specific religious dogma, if you will. For example, I don’t need any specific Catholic or Lutheran teaching to know I shouldn’t kill my neighbor for not mowing his lawn. Or beat a child, or lie in a store to get free goods, etc. I don’t want to dive in to a theological debate on the genesis of these social standards. At this point it is a given that most sane people follow these guidelines without needing any one specific religious authority to derive these behaviors. Call it common sense if you will.
More specifically, if you believe that ABC wrong, you can say it is because of the bible, or tradition, or even Catholic teaching. “The Catholic Church teaches that artificially contracepted sex is forbidden” is not something I could argue against you for believing. However, if you say “ABC is forbidden because of X”, this is something different. Now X is on the table, and needs to be clearly applicable to ABC, but not to NFP (assuming NFP is being held as acceptable practice). This is why St Francis’ argument, to me, holds no water. The “X” here is that ABC allows you to “take advantage of the pleasure without accepting the demands of the act”. Well that may be true. But I think it is plain as day that NFP also allows this to occur. Therefore it is NOT a distinguishing characteristic. Most of these types of statements rely on the assumption that contracepted sex is wrong. You can not make that assumption if that is question we are trying to answer. The same goes for many other X’s that are brought up. I don’t want to list them all, but many have come up in this thread. So to answer your question, the practical part of my statement is the “X” that is used to establish a position. If it is something we can observe here and now, it needs to be clearly true. I haven’t seen one yet that is.
Does that help explain my thinking at all?
