[UntoHim]

Gospelicious,

Your questions are very similar to the questions and concerns raised by Witness Lee and his followers over the past 50+ years. The problem is that these questions and concerns only exist among those dear brothers and sisters who have chosen to abandon the orthodox teachings that have been embraced by most of evangelical, orthodox protestant Christianity for about 2000 years now.

It is impossible to describe the Trinity in just a few sentences. However, that does not mean that there is not a need for safeguards to protect from heretical teachings. For better or for worse, this is what many of the creeds and statements of faith and theological declarations are all about. These long-standing creeds, statements and declarations are not to be considered on the same level as the Word of God, just as a fence around a home is not as important as the home - it is there to protect the home and it's precious occupants.

Allow me to post an excerpt from the Athanasian Creed:

We worship one God in Trinity, and Trinity in Unity; neither confounding the Persons, nor dividing the Essence. For there is one Person of the Father; another of the Son; and another of the Holy Spirit. But the Godhead of the Father, of the Son, and of the Holy Spirit, is all one; the Glory equal, the Majesty coeternal. Such as the Father is; such is the Son; and such is the Holy Spirit. The Father uncreated; the Son uncreated; and the Holy Spirit uncreated. The Father unlimited; the Son unlimited; and the Holy Spirit unlimited. The Father eternal; the Son eternal; and the Holy Spirit eternal. And yet they are not three eternals; but one eternal. As also there are not three uncreated; nor three infinites, but one uncreated; and one infinite.

Amazingly enough, even Wikipedia has a very biblical and succint definition of the orthodox view of the Trinity:
The Christian doctrine of the Trinity (Latin: Trinitas, lit. 'triad', from Latin: trinus "threefold") holds that God is one God, but three coeternal consubstantial persons or hypostases—the Father, the Son (Jesus Christ), and the Holy Spirit—as "one God in three Divine persons". The three persons are distinct, yet are one "substance, essence or nature" (homoousios). In this context, a "nature" is what one is, whereas a "person" is who one is.

Here is a short YouTube of the late Nabeel Qureshi explaining the orthodox view of the Trinity:
