I have discovered how to create a theological firestorm in an instant.
Put up a couple Instagram posts on the relationship between Jesus and the Holy Spirit, and see what happens.
To my relief, the discussion was a civilized one. I was struck by how many people are prepared to dive into a deep theological pool. Some were responding to wrong views they feel are being taught on the subject. Several comments indicated there are people who, whether they realize it or not, do not actually believe in the Trinity.
