This messianic people has Christ as its head: Christ who was given up for our sins and rose again for our justification; bearing now the name that is above every name, he reigns in glory in heaven. His people enjoy the dignity and freedom of the children of God, in whose hearts the Holy Spirit dwells as in a temple. They have as their law the new commandment of loving as Christ himself has loved us. They have as their goal the kingdom of God, begun on earth by God himself and destined to grow until it is also brought to perfection by him at the end of time, when Christ, our life, will appear, and creation itself will be freed from slavery to corruption and take on the freedom of the glory of God’s children… The Israel of old was already called the Church of God while it was on pilgrimage through the desert. So the new Israel, as it makes its way in this present age, seeking a city that is to come, a city that will remain, is also known as the Church of Christ, for he acquired it by his own blood, filled it with his Spirit, and equipped it with appropriate means to be a visible and social unity. God has called together the assembly of those who in faith look on Jesus, the author of salvation and the principle of unity and peace, and so has established the Church to be for each and all the visible sacrament of this unity which brings with it salvation.
