Location. Indianapolis is a pretty unique place with about 4 Spiritualist churches. They are basically all on different sides of the city. So if simply choosing the closest one and going there is enough, then more power to you.
Energy. So, you walk in the door and immediately feel something. What do you feel, is it good and welcoming? If you walk in the door and feel sick to your stomach, something is wrong here and you shouldn’t be here. If you walk in the door and feel instantly better. If you leave feeling better than ever, especially after a Spiritual Healing, you should keep coming back.
Music. A church has to have music. Music is one of the best ways to raise your vibration. Many churches sing songs out of old hymnals or homemade binders with an organist. You might find one that has modern music. You also have to wonder how legit the homemade binders are. You have to wonder how close they follow principle #7 (following laws), if they have homemade binders and you don’t see information about copyrights, public domain, being printed by permission, a CCLI license, etc.
Healing Service. One of the quickest ways to tell if a healer is good is if it seems to get hotter or cooler when you are around them. There are also cool healers but they are not near as common as healers that are hot when you are around them. If the healer asks you what’s wrong that might also be suspect. A healer who is also a medium may see Spirit guides healing the trouble spots and know where they are. A Spirit guide will probably finish with a full body healing just to be sure all is covered though. You should get up feeling better than ever before. The healing should keep you feeling better for a few days to a week.
