I just finished reading "Christ the Eternal Tao"

which is written by an Orthodox author and is actually more about Orthodoxy than Taoism and is pretty good. I found Orthodoxy at times appealing while reading it, but then they also engage in what I call "Mariolatry" by referring to Mary as "the Mother of God" and praying to her, which the Roman Catholics are also guilty of. 

The book also gets into "deification" or "divinization" which is like man becoming God or in union with God, which is something I certainly I never hear talked about in Western theology! It is said the early church father Irenaeus taught "God became man in order that man might become god" 😳 (but I haven't found a direct quote of this from Irenaeus yet). The apostle Peter did write that Christians have become "partakers of the divine nature" ( https://ref.ly/2Pe1.3-4 ). I will have to explore this idea further...
