Actually Ken, the only thing that link says is that there are Protestants who talk to catholics in an intimidating and patronising way.
You know, talk to and about them as if they are lesser beings, tell them that they are wrong, not Christian, don’t kow Jesus, don’t hear the Gospel… you know, the kind of stuff you always put in your posts about them.
My son is going out with a Catholic girl. I totally approve. He goes to a Baptist church but has been going to Mass as well (he is there right now) . I am delighted, that among other things, he has ditched the narrow mindedness that he was previously displaying. Not only in regards to Catholics, but also in regards to the Holy Land (ie; all the Arabs should just leave) and on Creationism (he was becoming avidly YECS).
If the difference between a couple, at their core beliefs is unresolvably vast, then there is a real reason to call the relationship off. But to assume, that the other is a Catholic, Orthodox or whatever, and not even go there is less about discretion and more about prejudice to my mind. You have absolutely no idea what a person believes until you get to know them. When people divide us into groups by our affiliation (this church, that race, this club, that part of town) then we are being divided at the most superficial level. I can guarantee you that if you really quizzed people in your own church (if you could do so without them feeling threatened or being inspected) then you will be shocked at what it is that they really believe.
In counselling work I found this to be true over and over again. A member, even Elder of a church who you are sure is straight down the line, has astonishing takes on doctrine, the Gospel, on God. But that won’t come out unless you have their trust and get to know them. Ken’s post is based on the presupposition that all members of a group are uniform or close to it. I doubt that to be true. It isn’t true of Catholics (many of them locally attend bible studies with other churches- esp. Anglicans- and we are in a Sydney type diocese), many others attend bible study at their own church. (yes Ken, they actually study the Bible)
