We know that God necessarily exists and that the act of creation was a sacrifice. We know that God did not create simply to be a mean child because this would mean he lacked something, but how do we know that he didn’t lack someone to love prior to creation?
It is only in the Trinity that we can explain how God is loving yet unchanging. It goes back to the distinction within the Trinity between the persons of God. If God is love, then God must have someone to love. Since creation took place at a point in time, while creation is indicative of God’s love, it cannot be the point where God began to love. Rather, if God is love, then he must have loved eternally, but this would be impossible if God were singular. In a Trinity, however, such a feat is possible.
The Father, being love, must love someone. In this love he must be sacrificial, hoping to gain nothing, but how can this be done absent of creation? The Father could love the Son and in loving the Son he could share everything he is with the Son, that is, he could make the Son equal to himself. What does the Father gain in making the Son equal? Nothing, but he sacrifices any potential selfishness or vainglory in doing so. The Son, being equal with the Father in all aspects, would willingly love the Father as much as the Father loves the Son. His sacrifice would come in following the will of the Father, though he could form his own will (this would later be demonstrated in the death of Christ).
But what is love between two when it can be shared? If a husband and wife refuse to share their love, then are they not selfish? I do not mean by having an open marriage, but by not having children. Or if they refuse to love anyone else because they are too focused on each other, would this not indicate selfishness? Likewise, with the Father and Son it follows that they would have a third person to love so that they may share in equality with this third person. This person is the Spirit.
The Spirit equally loves the Father and Son as they love him. All three are equals, love each other equally, and share in all attributes, save for being begotten and proceeding. We cannot explain how sacrifice exists within the Trinity, only to say that the Father holds the Son and Spirit as equal and that the Son and Spirit obey the will of the Father. Continue reading
