[11] And do this because you know the time; it is the hour now for you to awake from sleep. For our salvation is nearer now than when we first believed; [12] the night is advanced, the day is at hand. Let us then throw off the works of darkness (and) put on the armor of light; [13] let us conduct ourselves properly as in the day, not in orgies and drunkenness, not in promiscuity and licentiousness, not in rivalry and jealousy. [14] But put on the Lord Jesus Christ, and make no provision for the desires of the flesh.
(CCC 280) Creation is the foundation of "all God's saving plans," the "beginning of the history of salvation" (GCD 51) that culminates in Christ. Conversely, the mystery of Christ casts conclusive light on the mystery of creation and reveals the end for which "in the beginning God created the heavens and the earth": from the beginning, God envisaged the glory of the new creation in Christ (Gen 1:1; cf. Rom 8:18-23). (CCC 748) "Christ is the light of humanity; and it is, accordingly, the heart-felt desire of this sacred Council, being gathered together in the Holy Spirit, that, by proclaiming his Gospel to every creature, it may bring to all men that light of Christ which shines out visibly from the Church" (LG 1; cf. Mk 16:15). These words open the Second Vatican Council's Dogmatic Constitution on the Church. By choosing this starting point, the Council demonstrates that the article of faith about the Church depends entirely on the articles concerning Christ Jesus. The Church has no other light than Christ's; according to a favorite image of the Church Fathers, the Church is like the moon, all its light reflected from the sun. (CCC 2466) In Jesus Christ, the whole of God's truth has been made manifest. "Full of grace and truth," he came as the "light of the world," he is the Truth (Jn 1:14; 8:12; cf. 14:6). "Whoever believes in me may not remain in darkness" (Jn 12:46). The disciple of Jesus continues in his word so as to know "the truth [that] will make you free" and that sanctifies (Jn 8:32; cf. 17:17). To follow Jesus is to live in "the Spirit of truth," whom the Father sends in his name and who leads "into all the truth" (Jn 16:13). To his disciples Jesus teaches the unconditional love of truth: "Let what you say be simply 'Yes or No.'" (Mt 5:37).
