Hello everyone, I am fairly new to the Regulative Principle. From my understanding, it can be summarized in the following statement: only what God explicitly commands is permissible in the public and corporate worship of God on the Lord's Day. If that statement is incomplete or incorrect, please tell me. Applying this to a scenario, suppose that someone holds to a cappella exclusive psalmody (and in the interest of disclosure, this is not necessarily my position); on their own time outside of a worship service, would it be acceptable for them to play instruments and sing hymns--like from a Trinity Hymnal--or would that be dishonorable to God? Supposing that is permissible, what are passages in Scripture that justify this distinction between public and private worship? I am not questioning the RPW--I just want to be able to defend what it is I agree with and not follow blindly. There are so many threads on the RPW here and I am slowly trying to read through them. If there is one in particular that you think would be most relevant to my question, feel free to direct me to it.
