“‘And my Father will love him, and we will come to him and make our home with him’ [John 14.23]. My friends, consider the greatness of this solemn feast that commemorates God’s coming as a guest into our hearts! If some rich and influential friend were to come to your home, you would promptly put it all in order for fear something there might offend your friend’s eyes when he came in. Let all of us then who are preparing our inner homes for God cleanse them of anything our wrongdoing has brought into them.”
+ St. Gregory Dialogos, on Pentecost in Be Friends of God
