Discussion about the Trinity amongst Western Christians of all stripes tends to focus on the metaphysical issues raised by the oneness and threeness of God. Such speculation is of interest mainly to systematic theologians, with most other Christians content to accept the idea because that’s what Christians are supposed to believe (however irrational it may seem). The Trinity is therefore a matter for affirmation, but most leave it at that and focus on what seem to be more relevant matters, namely those that have to do with salvation. There are, of course, exceptions to this perspective, but I would contend that such exceptions prove the general rule among Protestants (and Catholics) in general and among Evangelicals in particular.
