So we have had quite a number of questions concerning verses that contain three 'persons' (or the like) and whether they teach the Trinity.
- Is 2 Corinthians 13:11-14 an assertion that God is three equal Persons?
- Should we understand God as three distinct persons based on (at least) Matthew 3:16-17?
- Is Paul referring to the Trinity in 1 Corinthians 12:4-6?
- Are three distinct persons mentioned in John 14:26?
A lot of these are simple questions of the format of "Does verse X imply the Trinity?" The problem with this is that a single verse is not enough to determine the doctrine of God. All of these verses, in isolation, can be read in ways that are compatible with the Trinity, with Modalism, with Arianism, with Mormonism, etc. It is only through reading them all together, along with many other verses that talk about one of the 'persons' but not necessarily all three, that we each determine our doctrine of God. That means that although these questions look like exegetical questions, they're actually theological synthesis questions. They don't belong here.
I propose that we make a canonical question that all of these are closed as duplicates of. We can quote several of the verses (Dottard has compiled a great list here).
Then, once it was asked, I suggest that we have one or two people answer to say that each of these verses can be read in a number of ways, but that we cannot simply read out from the text what the doctrine of God is. Maybe they could give a brief overview, one could overview the various doctrines of God that are out there. Another answer could caution against trying to read Paul and the other NT authors anachronistically; they didn't write after Nicaea, so we can't expect them to anticipate all the future theological debates. Perhaps they can link to Christianity.SE pages.
And then once the answers are there, I think we should close it.
Note that I am not saying all questions on these verses must be closed as a duplicate, just those that don't have any real depth to them. More specific questions would still be allowed, as long as they are truly exegetical questions.
