The Holy Trinity in Creation
God the Father created the world through the Son (Word) in the Holy Spirit. The Word of God is present in all that exists, making it to exist by the power of the Spirit. Thus, according to Orthodox doctrine, the universe itself is a revelation of God in the Word and the Spirit. The Word is in all that exists, causing it to be, and the Spirit is in all that exists as the power of its being and life.
This is most evident in God’s special creature, man. Man is made in the image of God, and so he bears within him the unique likeness of God which is eternally and perfectly expressed in the divine Son of God, the Uncreated and Absolute Image of the Father. Thus, man is “logical”; that is, he participates in God’s Logos (the Son and Word) and so is free, knowing, loving, reflecting on the creaturely level the very nature of God as the uncreated Son does on the level of divinity.
Man also is “spiritual”; he is the special temple of God’s Spirit. The Breath of God’s Life is breathed into him in the most special way. Thus, among creatures man alone is empowered to imitate God and to participate in His life. Man has the competence and ability to become a Son of God, mirroring the eternal Son, reflecting the divine nature because he is inspired by the Holy Spirit as is no other creature. Thus, one saint of the Church has said that for man to be a man, he must have the Spirit of God in him. Only then can he fulfill his humanity; only then can he be made a true Son of God, likened to him who is only-begotten.
On the most basic level of creation, therefore, we see the Trinitarian dimensions of the being and action of God: the Word and the Spirit of God enter man and the world to allow them to be and to become that for which the Father has willed their existence.
