How Do You Use Psalms?

Praying the psalms with your wife is a common practice. But how do you use them in marriage and church? Can we talk about what sorts of theological framers we ne have in mind when approaching them, before we get on to any practicalities? I think that's absolutely the right question to start with. There's plenty of people who haver, sometimes good and sometimes bad reasons, says said, we really shouldn't use these psalms. These just reflected attitude and missionary.
