"One of my big confusions during the first few years of my journey as an Orthodox Christian was caused by an assumption I had that words used by different Orthodox spiritual writers would refer to the same thing. It took me a few years and abundant consternation to finally figure out that, ... sometimes words take on slightly different meanings in one context than they have in another. Figuring this out the hard way cost me several years of headache wondering why apples sometimes looked more like oranges."
