"See Mayee! You see Mayee!" (boy refers to himself as "you")
"Yes, you see Mary." (he was in the hallway looking at an icon)
"Mayee (garblegarble) Tokos! Fay Tokos!"
"Yes, good job! Yes, Mary is the Theotokos!" (we had been working on that word)
"Fay Tokos mean Mama God."
"YES, Theotokos means Mother of God! Wow, you have been paying attention!"
"Mayee Fay Tokos Mama God!" (with that little "What a good boy I am!" giggle)
I think my little theologian deserves chocolate!
