CCC 703

The Word of God and his Breath are at the origin of the being and life of every creature: Cf. Pss 33:6; 104:30; Gen 1:2; 2:7; Eccl 3:20-21; Ezek 37:10. It belongs to the Holy Spirit to rule, sanctify, and animate creation, for he is God, consubstantial with the Father and the Son.... Power over life pertains to the Spirit, for being God he preserves creation in the Father through the Son. Byzantine liturgy, Sundays of the second mode, Troparion of Morning Prayer.
