It matters not what denomination or church anyone belongs to. What is important is that we all follow the Word of God and love and obey Him. In my opinion it is not up to any of us mere mortals to judge (although we can discern) any Christian. True believers will need to stick together against the forces of evil which are about to ramp up big time.
While I don't agree with everything Zone and Angela believe in and they don't agree with everything I write, but I trust that they are genuine Christians and most likely in a class far above the rank in file in their personal relationships with Jesus. I don't know much about the particulars of Lutheran theology but if they oppose the Pre-Trib Rapture, they are way ahead of my former Baptist denomination.
Anyone who takes to time to come on here and share their thoughts and views with other Christians in a positive way honors our Lord and Savior.
