The Trinity Doctrine: Help me out, Christians

[vulcanlogician]

I found an interesting tidbit looking this up on wikipedia

In the introduction to his 1964 translation of Meditations, the Anglican priest Maxwell Staniforth discussed the profound influence of Stoic philosophy on Christianity. In particular:

Again in the doctrine of the Trinity, the ecclesiastical conception of Father, Word, and Spirit finds its germ in the different Stoic names of the Divine Unity. Thus Seneca, writing of the supreme Power which shapes the universe, states, 'This Power we sometimes call the All-ruling God, sometimes the incorporeal Wisdom, sometimes the holy Spirit, sometimes Destiny.' The Church had only to reject the last of these terms to arrive at its own acceptable definition of the Divine Nature; while the further assertion 'these three are One', which the modern mind finds paradoxical, was no more than commonplace to those familiar with Stoic notions.

EDIT: This is interesting because Early Christianity often drew on Stoic philosophy in order to make its teachings more familiar to Roman gentiles whom the Christians were trying to convert.
