What concept describes the divine aspect of Jesus being merged with human nature?

The concept that describes the divine aspect of Jesus being merged with human nature is known as the Hypostatic Union. This theological term refers to the unique joining of two natures—divine and human—within one person, Jesus Christ. According to Christian doctrine, the Hypostatic Union asserts that Jesus is fully God and fully man, existing in one person without mingling or dilution of the two natures. This union is fundamental to understanding the mystery of the Incarnation, where the Word, or Logos, was made flesh.

In essence, the Hypostatic Union emphasizes both the integrity and distinctiveness of Jesus' divine and human natures, providing a framework for discussions about his life, work, and relationship with humanity. This concept has been central in addressing Christological heresies throughout history, affirming that while Jesus engaged with the human experience, he did so without losing his divine essence.

The other concepts mentioned, such as Monotheism, which refers to the belief in one God; Unity of Being, which pertains to the philosophical idea of a singular existence without distinction; and Incarnation, which is the broader term that describes God taking on human flesh, do not specifically encapsulate the coexistence of both natures
