Because of Adam’s sin we too are born “blind” but in the baptismal font we are illumined by the grace of Christ. Sin wounded humanity and destined it to the darkness of death, but the newness of life shines out in Christ, as well as the destination to which we are called. In him, reinvigorated by the Holy Spirit, we receive the strength to defeat evil and to do good.
In fact the Christian life is a continuous conformation to Christ, image of the new man, in order to reach full communion with God. The Lord Jesus is the “light of the world” (Jn 8:12), because in him shines “the knowledge of the glory of God” (2 Cor 4:6) that continues in the complex plot of the story to reveal the meaning of human existence.
In the rite of Baptism, the presentation of the candle lit from the large Paschal candle, a symbol of the Risen Christ, is a sign that helps us to understand what happens in the Sacrament. When our lives are enlightened by the mystery of Christ, we experience the joy of being liberated from all that threatens the full realization.
[Pope Benedict, Angelus 3 April 2011]
