There was talk of Constantine and the change of the Sabbath of course. Mostly it was talk of the Catholic Church during Constantines rule met and changed the worship day to Sunday. Then given to us if we wanted to follow the law of man or God. The Speaker probably 2 times every meeting stressed God has His lambs in every denomination. There was no real bigotry at all. I also do not feel any bigotry from my coworker who is a SDA.
I never meant to suggest anyone was a bigot. But you went to a prophesy seminar, and you were told you were worshiping on the wrong day, and had it put to you whether you would obey God or obey man. IOW: you went for one purpose, and got a low-key, but high-pressure sales pitch to convert faiths.
Some would consider the SDA dishonest for that.
