How best to analyse Moral Therapeutic Deism from the viewpoint of biblically-centered Reformed Protestantism?

I only heard this term a few days ago. Although I’ve had to go to various web-sites to try to find out about it, **I feel confusion growing and seek help from Reformed Protestants.** At first, I thought it was a more academic name for “Cultural Christianity” but apparently not – or is it? What gave rise to this phrase? Is there a specific year when it was written about, and was America the seed-bed for it (please don’t be offended at that question, all you Christian Americans on this site – it’s just that hundreds of ‘new’ religious movements all claiming to be Christian have sprung up there since the early 1800s to this very day.) ***So far, I gather that it teaches*** a god who created and watches over the earth and its people, wanting people to be nice to each other. But it is viewed as wrong to hold strong theological convictions (which are shunned and said to be harmful and judgemental, preventing equality amongst all religions, which seems to be its idea of a good thing). There is no repentance for sinning [which is an action of the will of the individual to go against God’s will], there is no idea of becoming a servant of Christ, or of devotion to prayer and Scripture reading. This leads to congregations where people do have a form of belief but do not have any understanding of their own religious traditions and what they are supposed to believe in order to be Christians. If they do understand their traditions, they simply don’t care to believe them and substitute whatever makes them feel good. ***Am I right with that brief summary?*** **The crucial matter for this analysis, though, is whether Moral Therapeutic Deism accords with orthodoxly Christian doctrine and practice.**
