In dealing with Calvinists in about 50 years as a Christian and more intensely in the last 40 years, I have found that they know what they are doing but they are doctrinaire in their stance.
Doctrinaire means that they are 'seeking to impose a doctrine in all circumstances without regard to practical considerations' (Oxford dictionaries 2016. S v doctrinaire). I find that they impose a Calvinistic doctrine on Scriptures and do not engage in careful exegesis of some Calvinistic texts. Yet, at other times I find they can be careful with exegesis. In my person library I have many Calvinistic commentators who give excellent insights on non-Calvinistic topic, but I have to read them as an Acts 17:11 Berean.
I know this from current practical experience. My wife and I attend an evangelical Presbyterian church and the pastor has admitted from the pulpit that his Reformed theology is sometimes doctrinaire. He used that word. He preached on Joshua 24:15 a couple of weeks ago and claimed that it was a choice between two evil options.
After the service, I challenged him on his poor exegesis in context, showing him that this was not the case when we read, Joshua 24:6-15, and discover that those were not the choices available.
Those choices were:
- They cried out to the Lord (v. 7).
- I would not listen to Baalam (v. 10).
- Fear the Lord and serve him; put away the gods (v. 14);
- Serve the Lord (v. 14);
- If it is evil to serve the Lord, choose this day whom you will serve - the gods your fathers served - BUT Joshua said he and his house would serve the Lord.
The Israelites had choices when it came to serving God/gods, i.e. they could choose between serving the other gods or fearing/serving the Lord.
That's not what my pastor preached from the pulpit. He gave only one choice - between the gods their fathers served beyond the River AND the gods of the Amorites. They were not the only choices that Joshua gave.
What I observed with the pastor was that his doctrinaire Calvinism was imposed on the text.
