Interesting note. I haven't studied Eastern Orthodox belief as much as simply Scripture. I don't find the word "enlightenment" or "enlightened" in Strong's Concordance, but simple searches regarding the word associated with spirit lead to New Age and numerous other belief systems outside of Christianity. I find issues such as spiritual baptism and new birth or rebirth or regeneration to be Scripturally based, but in the author's context, it appears he avoids that association in favor of an alternate religious belief.
"Interesting note. I haven't studied Eastern Orthodox belief as much as simply Scripture."
After the baptism, the newly baptized receives Holy Communion as the deacon or priest says, "The newly enlightened N. receives the Body and Blood of Christ."
