I. Jesus Christ established the Catholic Church during His time on earth, promising that she should last until the end of time. She was first made manifest at Pentecost, and has expanded to the ends of the world, united heaven and earth.

A. In the Old Covenant, God promised that there would be a new kingdom, which would extend to all of the world. See, e.g., Is. 2:2-4; Dan. 2:44-45; Micah 4:1-4.

1. In this new kingdom, all nations would be gathered together. See, e.g., Is. 66:28- 21; Jer. 3:17-18; Ps. 87:4-6.

2. This new and glorious kingdom would allow people to know God personally, a gift given only to the prophets, and in fact only at times even to them, in prior ages. See, e.g., Jer. 31:31-34; Ez. 36:26-27; Joel 3:1-2.

3. The kingdom would be guided by one glorious king, but also have other shepherds he appoints. See, e.g., Ez. 37:23-28; Jer. 3:15;

2. At Pentecost, the outpouring of the Spirit occurred and the Church began to gather the nations before into the kingdom of God. As the Catechism says, "The Church was made manifest to the world on the day of Pentecost by the outpouring of the Holy Spirit. The gift of the Spirit ushers in a new era in the dispensation of the mystery - the age of the Church, during which Christ manifests, makes present, and communicates His work of salvation through the liturgy of His Church until He comes." Catechism 1076.

D. The Church lives, not only on this earth, but also in heaven and in purgatory.

II. The Church on earth consists of the Latin rite and the Eastern rites, all of whom are under the Pope and governed by the successors to the Apostles, who are called bishops in the West.

III. The faithful in the world are called to vocations. The most common vocation is married life, which bring the sanctity of the Church to families. Some of the faithful are also called to consecrated single life, in which a man or woman is consecrated to prayerful service in the world.
