SYMEON THE NEW THEOLOGIAN (949–1022)
God does not show himself in a particular pattern or likeness, but in simplicity, and takes the form of an incomprehensible, inaccessible, and formless light. We cannot possibly say or express more than this; still God appears clearly and is consciously known and clearly seen, though invisible. God sees and hears invisibly and, just as friend speaks to friend face to face (cf. Ex. 33:11), so the One who by nature is God speaks to those whom by grace are begotten as gods. God loves like a father, and in turn is fervently loved by his children.
