“O blessed light, O Trinity and first Unity!”1 God is eternal blessedness, undying life, unfading light. God is love: Father, Son and Holy Spirit. God freely wills to communicate the glory of his blessed life. Such is the “plan of his loving kindness”, conceived by the Father before the foundation of the world, in his beloved Son: “He destined us in love to be his sons” and “to be conformed to the image of his Son”, through “the spirit of sonship”.2 This plan is a “grace [which] was given to us in Christ Jesus before the ages began”, stemming immediately from Trinitarian love.3 It unfolds in the work of creation, the whole history of salvation after the fall, and the missions of the Son and the Spirit, which are continued in the mission of the Church.4
The whole divine economy is the common work of the three divine persons. For as the Trinity has only one and the same natures so too does it have only one and the same operation: “The Father, the Son and the Holy Spirit are not three principles of creation but one principle.”5 However, each divine person performs the common work according to his unique personal property. Thus the Church confesses, following the New Testament, “one God and Father from whom all things are, and one Lord Jesus Christ, through whom all things are, and one Holy Spirit in whom all things are”.6 It is above all the divine missions of the Son’s Incarnation and the gift of the Holy Spirit that show forth the properties of the divine persons.
Being a work at once common and personal, the whole divine economy makes known both what is proper to the divine persons, and their one divine nature. Hence the whole Christian life is a communion with each of the divine persons, without in any way separating them. Everyone who glorifies the Father does so through the Son in the Holy Spirit; everyone who follows Christ does so because the Father draws him and the Spirit moves him.7
The ultimate end of the whole divine economy is the entry of God’s creatures into the perfect unity of the Blessed Trinity.8 But even now we are called to be a dwelling for the Most Holy Trinity: “If a man loves me”, says the Lord, “he will keep my word, and my Father will love him, and we will come to him, and make our home with him”:9
O my God, Trinity whom I adore, help me forget myself entirely so to establish myself in you, unmovable and peaceful as if my soul were already in eternity. May nothing be able to trouble my peace or make me leave you, O my unchanging God, but may each minute bring me more deeply into your mystery! Grant my soul peace. Make it your heaven, your beloved dwelling and the place of your rest. May I never abandon you there, but may I be there, whole and entire, completely vigilant in my faith, entirely adoring, and wholly given over to your creative action.10
