Dear Brothers and Sisters: In our catechesis on the Church, we have seen that God gathered a people to himself in the Old Testament and in the fullness of time sent his Son to establish the Church as the sacrament of unity for all humanity. God calls each of us to belong to this great family. None of us become Christians on our own; we owe our relationship with God to so many others who passed on the faith, who brought us for Baptism, who taught us to pray and showed us the beauty of the Christian life: our parents and grandparents, our priests, religious and teachers. But we are Christians not only because of others, but together with others. Our relationship with Christ is personal but not private; it is born of, and enriched by, the communion of the Church. Our shared pilgrimage is not always easy: at times we encounter human weakness, limitations and even scandal in the life of the Church. Yet God has called us to know him and to love him precisely by loving our brothers and sisters, by persevering in the fellowship of the Church and by seeking in all things to grow in faith and holiness as members of the one body of Christ.
