See, we would not say that there are three different natures. There are three distinct persons, but there is just one essence.

Now if you had been talking about Jesus alone, then I would have ceded you the point that Jesus himself had two different natures, a human nature and a divine nature. But God has only one nature, one essence, one substance, one being no matter which of the three distinct personas you speak of the Father, the Son, the Holy Spirit.
