"Thou art Peter, and upon this rock, I will build my Church, and the gates of Hell shall not prevail against it." These words of Our Savior in Matthew 16:18 form the core of the Catholic Church's claim to be the one, true Church founded by Jesus Christ: Ubi Petrus, ibi ecclesia—"Where Peter is, there is the Church." The Pope, the successor of Peter as bishop of Rome, is the sure sign that the Catholic Church remains the Church of Christ and His apostles.

seven sacraments are the center of our life as Christians. Our baptism removes the effects of Original Sin and brings us into the Church, the Body of Christ. Our worthy participation in the other sacraments provides us with the grace we need to conform our lives to Christ and marks our progress through this life. Each sacrament was instituted by Christ during His life on earth and is an outward sign of an inward grace.
Christmas is the most important day in the Catholic liturgical calendar, but from the earliest days of the Church, Easter has been considered the central Christian feast. As Saint Paul writes in 1 Corinthians 15:14, "If Christ has not been raised, then our preaching is in vain and your faith is in vain." Without Easter—without the Resurrection of Christ—there would be no Christian Faith. Christ's Resurrection is the proof of His Divinity.
Pentecost Sunday is not far behind. Coming 50 days after Easter and ten days after the Ascension of Our Lord, Pentecost marks the descent of the Holy Spirit on the apostles. For that reason, it is often called the "the birthday of the Church."
