I would like to draw your attention to a few aspects of this beautiful structure which I think can serve as a starting point for a reflection on our particular vocations within the unity of the Mystical Body.
The first has to do with the stained glass windows, which flood the interior with mystic light. From the outside, those windows are dark, heavy, even dreary. But once one enters the church, they suddenly come alive; reflecting the light passing through them, they reveal all their splendor. Many writers – here in America we can think of Nathaniel Hawthorne – have used the image of stained glass to illustrate the mystery of the Church herself. It is only from the inside, from the experience of faith and ecclesial life, that we see the Church as she truly is: flooded with grace, resplendent in beauty, adorned by the manifold gifts of the Spirit. It follows that we, who live the life of grace within the Church’s communion, are called to draw all people into this mystery of light.
This is no easy task in a world which can tend to look at the Church, like those stained glass windows, “from the outside”: a world which deeply senses a need for spirituality, yet finds it difficult to “enter into” the mystery of the Church. Even for those of us within, the light of faith can be dimmed by routine, and the splendor of the Church obscured by the sins and weaknesses of her members. It can be dimmed too, by the obstacles encountered in a society which sometimes seems to have forgotten God and to resent even the most elementary demands of Christian morality. You, who have devoted your lives to bearing witness to the love of Christ and the building up of his Body, know from your daily contact with the world around us how tempting it is at times to give way to frustration, disappointment and even pessimism about the future. In a word, it is not always easy to see the light of the Spirit all about us, the splendor of the Risen Lord illuminating our lives and instilling renewed hope in his victory over the world (cf. Jn 16:33).
Yet the word of God reminds us that, in faith, we see the heavens opened, and the grace of the Holy Spirit lighting up the Church and bringing sure hope to our world. “O Lord, my God,” the Psalmist sings, “when you send forth your spirit, they are created, and you renew the face of the earth” (Ps 104:30). These words evoke the first creation, when the Spirit of God hovered over the deep (cf. Gen 1:2). And they look forward to the new creation, at Pentecost, when the Holy Spirit descended upon the Apostles and established the Church as the first fruits of a redeemed humanity (cf. Jn 20:22-23). These words summon us to ever deeper faith in God’s infinite power to transform every human situation, to create life from death, and to light up even the darkest night. And they make us think of another magnificent phrase of Saint Irenaeus: “where the Church is, there is the Spirit of God; where the Spirit of God is, there is the Church and all grace” (Adv. Haer. III, 24, 1).
