Hypostasis is the Greek word for "substance"
The Hypostatic Union is the doctrine dealing with the nature of Jesus.
Here is the actual statement:
Therefore, following the holy fathers, we all with one accord teach men to acknowledge one and the same Son, our Lord Jesus Christ, at once complete in Godhead and complete in manhood, truly God and truly man, consisting also of a reasonable soul and body; of one substance with the Father as regards his Godhead, and at the same time of one substance with us as regards his manhood; like us in all respects, apart from sin; as regards his Godhead, begotten of the Father before the ages, but yet as regards his manhood begotten, for us men and for our salvation, of Mary the Virgin, the God-bearer; one and the same Christ, Son, Lord, Only-begotten, recognized in two natures, without confusion, without change, without division, without separation; the distinction of natures being in no way annulled by the union, but rather the characteristics of each nature being preserved and coming together to form one person and subsistence, not as parted or separated into two persons, but one and the same Son and Only-begotten God the Word, Lord Jesus Christ; even as the prophets from earliest times spoke of him, and our Lord Jesus Christ himself taught us, and the creed of the fathers has handed down to us.
The part of thus doctrine that has been challenged recently is that Jesus is recognized in two natures, without confusion, without change, without division, without separation; the distinction of natures being in no way annulled by the union, but rather the characteristics of each nature being preserved and coming together to form one person and subsistence, not as parted or separated into two persons, but one and the same Son and Only-begotten God the Word, Lord Jesus Christ.
We often represent this by saying Jesus is 100% God, 100% man.
Recently @SavedByGrace and @37818 have suggest a different view - that Jesus has two natures (one being 100% God and the other being 100% man with Jesus adding a human nature as a second nature).
This, obviously, contradicts orthodox Christianity. Rather than Jesus being represented in the union of two natures in one substance, you end up with Jesus having one 100% God nature and one 100% human nature (50% God and 50% man).
Mathematically this makes sence. But Biblically I do not believe they can support the position.
