Enhypostasia is a Greek term used to describe the belief that Christ's humanity and divinity existed in one person, with the divine nature being the only true nature. This theological concept has been the subject of much debate over the centuries. There are a few synonyms for enhypostasia, including the hypostatic union and the communication of idioms. The hypostatic union emphasizes the idea that Christ's two natures are united in one person, while the communication of idioms highlights the fact that Christ's divine and human natures share attributes or qualities. Both of these synonyms are closely related to enhypostasia and continue to be studied by theologians today.
