The foundation stone of a church is a symbol of Christ. The Church rests on Christ, is sustained by him and cannot be separated from him. He is the one foundation of every Christian community, the living stone, rejected by the builders but chosen and precious in God’s sight as the cornerstone (cf. 1 Pet 2:4-5, 7). With him, we too are living stones built into a spiritual house, a dwelling place for God (cf. Eph 2:20-22; 1 Pet 2:5). Saint Augustine loved to refer to the mystery of the Church as the Christus totus, the whole Christ, the full or complete Body of Christ, Head and members. This is the reality of the Church; it is Christ and us, Christ with us. He is with us as the vine is with its own branches (cf. Jn 15:1-8). The Church is in Christ a community of new life, a dynamic reality of grace that flows from him. Through the Church Christ purifies our hearts, enlightens our minds, unites us with the Father and, in the one Spirit, moves us to a daily exercise of Christian love. We confess this joyful reality as the One, Holy, Catholic and Apostolic Church.
We enter the Church through baptism. The memory of Christ’s own baptism is brought vividly before us in this place. Jesus stood in line with sinners and accepted John’s baptism of penance as a prophetic sign of his own passion, death and resurrection for the forgiveness of sins. Down through the centuries, many pilgrims have come to the Jordan to seek purification, renew their faith and draw closer to the Lord. Such was the pilgrim Egeria, who left a written account of her visit during the late fourth century. The Sacrament of Baptism, drawing its power from Christ’s death and resurrection, will be cherished especially by the Christian communities that gather in the new church buildings. May the Jordan always remind you that you have been washed in the waters of baptism and have become members of the family of Jesus. Your lives, in obedience to his word, are being transformed into his image and likeness. As you strive to be faithful to your baptismal commitment of conversion, witness and mission, know that you are being strengthened by the gift of the Holy Spirit.Excerpts from Pope Benedict's blessing of the foundation stones of the Latin and Greek Melkite churches at Bethany beyond the Jordan (May 10, 2009)
