Definition: It appears you're asking about the term "transubstantiation", which refers to the doctrine that Jesus Christ, after his ascension to Heaven, was no longer God but His body and blood had been transferred into human flesh, thereby becoming both a man and a woman. The concept of transubstantiation is not universally accepted by all Christian traditions. Some believe it to be an allegory, while others see it as a literal statement that Jesus was both divine and mortal. Additionally, there are some who question whether God or humanity could ever become truly human or even capable of becoming the same person again. Overall, transubstantiation is considered an important theological concept in Christian theology and can have different interpretations depending on one's perspective and understanding of the Bible.
