Most evangelicals would recognize & reject occult practices like mediums, the Ouija board, etc. knowing the Bible condemns and calls this an abomination. But sadly thousands without knowing are embracing occult practices by accepting mystical Spiritual Exercises. As an ex-Catholic it breaks my heart to see evangelicals following Catholic saints or their mystical teachings.
It is very important to examine what is the spirit behind any spiritual practice 1 John 4:1 before we open the door & welcome them 2 Jn.1:10. Some people will say that what they are learning is in the Bible, but beloved please remember satan is a master of deception! Always check who were the mentors of that teacher, or where their doctrine came from. One of the most used mystic exercises belong to Jesuit founder Ignatius of Loyola.
