The Trinity: What the Big Deal?

In one of our recent Adult Bible Fellowships we discussed the doctrine of the Trinity in relation to specific cults and I thought it may be helpful to give a lengthy quotation as to why it’s important to believe it the Trinity:

Why is the church so concerned about the doctrine of the Trinity? Is it really essential to hold to the full deity of the Son and the Holy Spirit? Yes it is, for this teaching has implication for the very heart of the Christian faith.

First, the atonement is at stake. If Jesus is merely a created being and not fully God, then it is hard to see how he, a creature, could bear the full wrath of God against all of our sins. Could any creature, no matter how great, really save us?

Second, justification by faith alone is threatened if we deny the full deity of the Son. (This is seen today in the teaching of the JW’s who do not believe in justification by faith ALONE.)  If Jesus is not fully God, we would rightly doubt whether we can really trust him to save us completely. Could we really depend on any creature fully for our salvation?

Third, if Jesus is not infinite God, should we pray to him or worship Him? Who but an infinite, omniscient God could hear and respond to all the prayers of God’s people? And who but God himself is worthy of worship? Indeed, if Jesus is merely a creature, no matter how great, it would be idolatry to worship him – yet the NT commands us to do so (Phil 2.9-11; Rev 5.12-14).

Fourth, if someone teaches that Christ was a created being but nonetheless one who saved us, then this teaching wrongly begins to attribute credit for salvation a creature and not to God himself. But this wrongfully exalts the creature rather than the Creator, something Scripture never allows us to do.

Fifth, the independence and personal nature of God are at stake: If there is no Trinity, then there were no interpersonal relationships within the being of God before creation, and, without personal relationships, it is difficult to see how God could be genuinely personal or be without the need for a creation to relate to.

Sixth, the unity of the universe is at stake: If there is not perfect plurality and perfect unity in God himself, then we have no basis for thinking there can be any ultimate unity among the diverse elements of the universe either. Clearly, in the doctrine of the Trinity, the heart of the Christian faith is at stake.
