Christians gravitate towards one of two positions-three gods,- or one God with three different aspects father, son, holy ghost. [The first is not okay.] But both positions are considered heresy for Christians.[Sabellianism, Arianism] With Boethius, they came up with what they think is a middle position: One essence and three persons. But regardless of this being thought to be correct, an individual Christian in his or her thought gravitates towards either of the first two positions, i.e. three different powers, or just One Power with different aspects.
I think a lot depends on which gospel they read first--Mathew or Luke. The first is deeply imbedded in the Old Testament ;, and Old Testament theology is Monotheism: One God only, and who is totally beyond anything that humans can conceive. Totally :"other".
Paul is more along the lines of the later approach which is not very rooted in the Old Testament. And Luke and Acts were written by a disciple of Paul.
[I am not very happy with the idea of aspects of God, however you do find this in the Ari and Moshe of Cordoba.]
[I should add here that not only the issues mentioned above but also the role of Jesus is an argument between the authors of the \gospels.]
