From a sermon on the transfiguration of the Lord by Anastasius of Sinai, bishop
Let us be caught up like Peter to behold the divine vision and to be transfigured by that glorious transfiguration. Let us retire from the world, stand aloof from the earth, rise above the body, detach ourselves from creatures and turn to the creator, to whom Peter in ecstasy exclaimed: Lord, it is good for us to be here.
It is indeed good to be here, as you have said, Peter. It is good to be with Jesus and to remain here for ever. What greater happiness or higher honour could we have than to be with God, to be made like him and to live in his light?
Therefore, since each of us possesses God in his heart and is being transformed into his divine image, we also should cry out with joy: It is good for us to be here – here where all things shine with divine radiance, where there is joy and gladness and exultation; where there is nothing in our hearts but peace, serenity and stillness; where God is seen. For here, in our hearts, Christ takes up his abode together with the Father, saying as he enters: Today salvation has come to this house. With Christ, our hearts receive all the wealth of his eternal blessings, and there where they are stored up for us in him, we see reflected as in a mirror both the first fruits and the whole of the world to come.
