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 DamascusThe whole earth is a living icon of the face of God. ... I do not worship matter. I worship the Creator of matter who became matter for my sake, who willed to take His abode in matter, who worked out my salvation through matter. Never will I cease honoring the matter which wrought my salvation! I honor it, but not as God. Because of this I salute all remaining matter with reverence, because God has filled it with his grace and power. Through it my salvation has come to me.
John of DamascusBoth angels and demons are ignorant of the future, yet they make predictions. The angels do so when God reveals the future to them and commands them to prophesy, and what they prophesy comes to pass. Demons also make predictions, but these are only guesses based on what they see from afar.
John of DamascusThe saints must be honored as friends of Christ and children and heirs of God. Let us carefully observe the manner of life of all the apostles, martyrs, ascetics, and just men who announced the coming of the Lord. And let us emulate their faith, charity, hope, zeal, life, patience under suffering, and perseverance unto death so that we may also share their crowns of glory.
