The Trinity (18)

To conclude this series on the Trinity, the Father possesses the whole nature of God as His Own, the Son possesses the whole nature of God as His Own, the Holy Spirit possesses the whole nature of God as His Own. And since the nature of any being decides what the being is, each person is God, wholly and therefore equally with the others. Further, the nature decides what the person can do: therefore, each of the three persons who thus totally possess the Divine Nature can do all the things that go with being God.

CCC 2205 states:

The Christian family is a communion of persons, a sign and image of the communion of the Father and the Son in the Holy Spirit.

When we think of a family, we can see how a father, mother, and child can be distinct persons and yet possess the same nature (human), just as the Father, Son, and Holy Spirit are three distinct persons who each possess the same nature (divine). The weakness, of course, is that in God each person possesses the one infinite and immutable divine nature, and is therefore, one being. Our analogous family consists of three beings. Again, no analogy is perfect. But in the end, if we combine our two analogies, we can at least see both how there can be three relationally distinct realities subsisting within one being in the anthropological analogy, and how there can be three relationally distinct persons who share the same nature in the analogy of the family.

In Christ, Ken.
