When I was a Christian, I believed in the
hypostatic union, which is the theological belief that Jesus took on human nature yet remained fully God when he was a man. It encapsulates the belief regarding his humanity and divinity (
two natures) in a single hypostasis and is in conjunction with the
Trinity doctrine.
As a former Christian evangelist, I know that many evangelicals don't consider Jehovah's Witnesses to be true Christians, but rather misguided people who hold false beliefs, distort and misinterpret the Bible, and teach unbiblical doctrines (e.g.,
"Who are the Jehovah’s Witnesses and what are their beliefs?").
I believed the same when I was an evangelical. In fact, I considered them to be among the least knowledgeable of the Bible during my many years as an evangelist and street preacher. It became apparent to me that their knowledge of the Bible was restricted to their church's approved interpretation and sanctioned teachings. I received training as a street preacher to specifically target them and attempt to convert them to my evangelical-centered version of Christianity. In fact, the belief that JWs (as well as LDS Mormons and Roman Catholics) weren't genuine Christians was an integral part of my training. I was equipped with specific gospel tracts and other materials that informed me about their beliefs, along with instructions on how to lead them to Christ.
