"When the fullness of time had come, God sent his Son, [...] in order to redeem those who were under the law, so that we might receive adoption as children. As proof that you are children, God has sent the Spirit of his Son into our hearts, crying out, "Abba! Father!". So you are no longer a slave but a child, and if a child then also an heir, through God." (Galatians 4:4-7)

"Beloved, we are God's children now; what we shall be has not yet been revealed. We do know that when it is revealed we shall be like Him, for we shall see Him as He is." (1 John 3:2)

"God the Father has blessed us in Christ with every spiritual blessing in heaven, as He chose us in Him, before the foundation of the world, to be holy and without blemish before Him. In love, He destined us for adoption to Himself through Jesus Christ, in accord with the favor of His will." (Ephesians 1: 3-5)

God the Father predestined us to become His children, and in His Son, Jesus, He endowed us with a new dignity of the royal heirs, who share in the freedom, joy, and happiness of the life of the Holy Trinity (Rom 8:17; Eph 1:4-6). This is our true identity and our destiny!

Divine filiation - divine sonship - is the Christian doctrine that Jesus Christ is the only-begotten Son of God by nature, and when Christians are redeemed by Jesus they become sons (and daughters) of God by adoption (1 John 3:1-2, 2 Peter 1:4) [1].

Divine filiation is at the core of Christianity. "Our divine filiation is the centerpiece of the Gospel as Jesus preached it. It is the very meaning of the salvation He won for us. For he did not merely save us from our sins; He saved us for sonship." [2]

In fact, the name 'Christian' indicates a new way of being, to be in the likeness of the Son of God. As sons in the Son, we share in salvation, which is not only the deliverance from evil, but is first of all the fullness of good: of the supreme good of the sonship of God" [3]. "We can adore the Father because he has caused us to be reborn to his life by adopting us as his children in his only Son: .. through the anointing of his Spirit who flows from the head to the members, he makes us other "Christs." " who have become sharers in Christ are appropriately called "Christs." [4]

The divinization of man through sonship is real and metaphysical. It is not metaphorical, i.e. a mere comparison with a real thing that is similar. In the Christian religion, God is really the Father and does not just act like human fathers. And God really made us to share in his nature, and thus we are really children. Not at the same level as the Only Begotten Son, but truly sharing in his filiation and his divinity [3].​

What does it mean to us to be God's heirs?

Since divine filiation is fundamental for the Christian life, a foundational point, then the various aspects of the Christian life follow from it, as shown by the frequent allusions of the Catechism to divine filiation:

  • Abandonment to the Father's providence, since Jesus said that "your heavenly Father knows what you need." (Mt 6:31; CCC 305) [1,2]. Thus Benedict XVI said in Deus Caritas Est, "Immersed like everyone else in the dramatic complexity of historical events, [Christians] remain unshakably certain that God is our Father and loves us, even when his silence remains incomprehensible." [3]

  • Becoming child-like in piety, because it is a condition for entering the Kingdom. (Mt 18:3-4; CCC 526)

  • Confidence to call God "Father" and asking him for gifts. "Our Father: at this name love is aroused in us . . . and the confidence of obtaining what we are about to ask.... What would He not give to his children who ask, since he has already granted them the gift of being his children?"

  • Viewing the liturgy as "a meeting of God's children with their Father, in Christ and the Holy Spirit." (CCC 736; 1153)

  • Loving the Church, for God "gathers all his children into unity." (CCC 845), and the Church is "the house of all God's children, open and welcoming". (CCC 1186). And with this the Christian keeps the communion of the saints. (CCC1474)

  • Giving importance to baptism, by which the Christian becomes a child of God. (CCC 1243). The Christian should realize the "greatness of God's gift... by the sacraments of rebirth, Christians become children of God, partakers of the divine nature." (CCC 1692)​

  • ​​Playing the role of the prodigal son. Because the "new life as a child of God can be weakened and even lost by sin," (CCC 1420) the Christian has the sacrament of healing called the sacrament of Reconciliation which "bring about the restoration of the dignity and blessings of the life of the children of God, of which the most precious is friendship with God." (CCC 1468) "The whole of the Christian life," says John Paul II in his first encyclical Redemptor Hominis, "is like a great pilgrimage to the house of the Father, whose unconditional love for every human creature, especially for the "prodigal son", we discover anew each day." [4]

  • Living in imitation of Christ: "Following Christ and united with him, Christians can strive to be "imitators of God as beloved children, and walk in love" by conforming their thoughts, words, and actions to the "mind . . . which is yours in Christ Jesus," and by following his example." (CCC 1694)

  • Practicing obedience. "Although he was a Son, [Jesus] learned obedience through what he suffered. How much more reason have we sinful creatures to learn obedience - we who in him have become children of adoption." (CCC 2825)
