When man accepts the Spirit of Christ, he establishes a way of life that is totally new and gratuitous. The Holy Spirit, present in the soul of the Christian, makes him a partaker of the divine nature and intimately unites him ho the Father and Christ in a communion of life which net even death can break (cf. John 14, 23). The Holy Spirit heals man of his spiritual weaknesses and infirmities, frees him from the slavery of his passions and of immoderate self-love, by giving him power to keep the divine law, strengthens him with hope and fortitude, enlightens him in the pursuit of the good, and infuses in him the frumps of charity, joy, peace, patience, kindness, goodness, longanimity, humility, fidelity, modesty, continence, and chastity (cf. Gal. 5, 22-23). This is why the Holy Spirit is invoked as the guest of the soul. Justification from sin and God’s indwelling in the soul are a grade. When we say a sinner is justified by God, is given life by the Holy Spirit, possesses in himself Christ's life, or has grade, we are using expressions which in different words mean one and the same thing, namely, dying to sin, becoming partakers of the divinity of the Son borough the Spirit of adoption, and entering into an intimate communion with the most Holy Trinity. The man belonging b the history of salvation is the man ordered to the grace of filial adoption and to eternal life. Christian anthropology finds its own proper character in the grace of Christ the Savior.
