I am sorry you feel that way. I do not necessarily respect nor disrespect a particular "religion" if I take communion in any church, RC or not. I can not think of anywhere in Scripture where it says we are to "respect" other's people religions. Do you know of any? Nor does it say it is wrong to be disrespectful of them. In fact, I would think it is right in His eyes if I were to go into a Mormon church or a buddist temple or Islamic mosque and be "respectful" of their religion.
My faith is in the Lord Jesus Christ. I hope that yours is also. It would seem as if you are trying to judge my motives. You don't know my heart, nor do I know yours, but we can be confident that He knows our hearts and if we are abiding in Him, then if we are sinning against him, we can know they He will expose the wrong motives of our hearts. We can't.
I won't get into the theological discussions
I won't either. (Biblical - perhaps, if people are willing to do so under Him.) They have been done ad nauseum over many centuries.
I didn't belong and I disagreed with their beliefs and I knew they ask that I don't partake in something crucial and sacred for them, then, out of respect, I would remain silent and still.
That is you. But we must all go as the Lord leads. And, you also do not know of all the circumstances.
I'm sure no one 'freak's out' when you say "thank you", but I am sure they are taken aback somewhat.
"Freak out" was probably the wrong term to use. But there was a look of almost panic on the face - it had a very definite element of fear. I know the person. And yes, I know enough of what you are "supposed" to say and how you are to hold your hands, and all of that. I just choose not to do or say that because I don't believe it has anything to do with my walk with the Lord and you are right - I can't be a hypocrite. I don't say it because I do not believe that saying a particular word or phrase means anything. God looks at the heart. He always has, He always will.
