Our Lord humbled without humiliation His lofty station which yet could not be humbled, and condescends to His servants, with a condescension ineffable and incomprehensible. God being perfect becomes perfect man, and brings to perfection the newest of all new things (cf. Eccles 1:10), the only new thing under the sun, through which the boundless might of God is manifested. For what greater thing is there than that God should become man?
John of DamascusThink of the Father as a spring of life begetting the Son like a river and the Holy Ghost like a sea, for the spring and the river and sea are all one nature. Think of the Father as a root, and of the Son as a branch, and the Spirit as a fruit, for the substance in these three is one. The Father is a sun with the Son as rays and the Holy Ghost as heat.
John of DamascusHe who does not believe according to the tradition of the Catholic Church is an unbeliever.
