Hashi Al-Eritre:
From what i have gathered thus far is the main proof for the rationality of the trinity and how it works is maintaining God’s Omnipresence, because this is the only way to maintain God’s oneness in essence. This forum is actually the first time ive ever heard Christians believe God is omnipresent.
However, i see there is some disagreement among the posters here and in other threads regarding the manner in which God is omnipresent. Some are saying he is everywhere and in everything, and others (noteably itsjustdave) saying God isnt everywhere but he is present in holy places and where he chooses. I would like to see some consensus to this because it really is a vital part of your doctrine and how you call to belief in God.
Here is what the Catholic Encyclopedia says about Gods omnipresence. It is accepted by the bishops.
B. IMMENSITY AND UBIQUITY, OR OMNIPRESENCE
Space, like time, is one of the measures of the finite, and as by the attribute of eternity, we describe
God’s transcendence of all temporal limitations, so by the attribute of immensity we express His transcendent relation to space. There is this difference, however, to be noted between eternity and immensity, that the positive aspect of the latter is more easily realized by us, and is sometimes spoken of, under the name of omnipresenee, or ubiquity, as if it were a distinct attribute. Divine immensity means on the one hand that
God is necessarily present everywhere in space as the immanent cause and sustainer of creatures, and on the other hand that He transcends the limitations of actual and possible space, and cannot be circumscribed or measured or divided by any spatial relations. To say that
God is immense is only another way of saying that He is both immanent and transcendent in the sense already explained. As some one has metaphorically and paradoxically expressed it, “
God’s centre is everywhere, His circumference nowhere.” That
God is not subject to spatial limitations follows from His infinite simplicity; and that He is truly present in every place or thing – that He is omnipresent or ubiquitous – follows from the fact that He is the cause and ground of all reality. According to our finite manner of thinking we conceive this presence of
God in things spatial as being primarily a presence of power and operation – immediate Divine efficiency being required to sustain created beings in existence and to enable them to act; but, as every kind of Divine action
ad extra is really identical with the Divine nature or essence, it follows that
God is really present everywhere in creation not merely
per virtuten et operationem, but
per essentiam. In other words
God Himself, or the Divine nature, is in immediate contact with, or immanent in, every creature – conserving it in being and enabling it to act. But while insisting on this truth we must, if we would avoid contradiction, reject every form of the pantheistic hypothesis. While emphasizing Divine immanence we must not overlook Divine transcendence.

As the above mentions, Gods presence is what holds everything together. God is in everything in His entirety. He is completely in the flower that you see in a field and in all of His creation. But at the same time He transcends time and space.
