“… I was given another parrot… It was also wild to begin with just like the first one. In the same way with prayer and gentleness I tamed this one. It started gradually to say various words, to squawk out names, to come out of its cage, to sit on my shoulder and to eat with me.… Now that we became very good friends it’s learned not only words and names but it says the prayer: “Lord Jesus Christ have mercy on me.” It also says “O Virgin  who brought forth God, Hail Mary full of grace the Lord is with you, God is good, and it knows how to sing “Lord have mercy” and other things.”
(St Elder Porphyrios in ‘Wounded by Love’)
