This would also largely apply to the Greek / Russian Orthodox, JW's , Mormons & 7th Day Adventists, as they believe in God but trust in tradition, works, wrongly translated Scripture, wrong interpretations & commentaries (I would even include Hyper Calvinists in this category) & other "sacred" writings & making them equal or higher than the Biblical final authority.If you are going to share the Gospel with Catholics etc, stop making the mistake of starting with Mary, statues, candles, the pope,
