Poverty and Humility.—The ancients thought that riches ennobled a man and they regarded pride as a worthy sentiment. "Blessed are the poor," said Christ, "for theirs is the kingdom of heaven." He that would not renounce all that he had could not be his disciple. He himself went from city to city, possessing nothing, and when his disciples were preoccupied with the future, he said, "Be not anxious for what ye shall eat, nor for what ye shall put on. Behold the birds of the heaven, they sow not neither do they reap, yet your heavenly Father feedeth them."
The Christian was to disdain riches, and more yet, worldly honors. One day when his disciples were disputing who should have the highest rank in heaven, he said, "He that is greatest among you shall be your servant." "Whosoever exalteth himself shall be abased, and he that humbleth himself shall be exalted." Till our day the successor of Saint Peter calls himself "Servant of the servants of God." Christ drew to himself by preference the poor, the sick, women, children,—in a word, the weak and the helpless. He took all his disciples from among the populace and bade them be "meek and lowly of heart."
The Kingdom of God.—Christ said that he had come to the earth to found the kingdom of God. His enemies believed that he wished to be a king, and when he was crucified, they placed this inscription on his cross, "Jesus of Nazareth, king of the Jews." This was a gross mistake. Christ himself had declared, "My kingdom is not of this world." He did not come to overturn governments nor to reform society. To him who asked if he should pay the Roman tax, he replied, "Render unto Cæsar the things that are Cæsar's, and to God the things that are God's." And so the Christian accepted what he found established and himself worked to perfect it, not to remodel society. To make himself pleasing to God and worthy of his kingdom it was not necessary to offer him sacrifices or to observe minute formulas as the pagans did: "True worshippers shall worship the Father in spirit and truth." Their moral law is contained in this word of Christ: "Be ye therefore perfect even as your Father which is in heaven is perfect."
THE FIRST CENTURIES OF THE CHURCH
Disciples and Apostles.—The twelve disciples who associated with Christ received from him the mission to preach his doctrine to all peoples. From that time they were called Apostles. The majority of them lived in Jerusalem and preached in Judæa; the first Christians were still Jews. It was Saul, a new convert, who carried Christianity to the other peoples of the Orient. Paul (for he took this name) spent his life visiting the Greek cities of Asia, Greece, and Macedonia, inviting to the new religion not only the Jews, but also and especially the Gentiles: "You were once without Christ," said he to them, "strangers to the covenant and to the promises; but you have been brought nigh by the blood of Christ, for it is he who of two peoples hath made both one." From this time it was no longer necessary to be a Jew if one would become a Christian. The other nations, disregarded by the law of Moses, are brought near by the law of Christ. This fusion was the work of St. Paul, also called the Apostle to the Gentiles.
The religion of Christ spread very slowly, as he himself had announced: "The kingdom of heaven is like a grain of mustard-seed ... which is the least of all seeds; but when it is grown, it is the greatest among herbs ... and the birds of the air lodge under its branches."
The Church.—In every city where Christians were found they assembled to pray together, to sing the praises of God, and to celebrate the mystery of the Lord's Supper. Their meeting was called Ecclesia (assembly). Usually the Christians of the same assembly regarded themselves as brothers; they contributed of their property to support the widows, the poor, and the sick. The most eminent directed the community and celebrated the religious ceremonies. These were the Priests (their name signifies "elders"). Others were charged with the administration of the goods of the community, and were called Deacons (servants). Besides these officers, there was in each city a supreme head—the Bishop (overseer).
Later the functions of the church became so exacting that the body of Christians was divided into two classes of people: the clergy, who were the officials of the community; the rest, the faithful, who were termed the laity.
Each city had its independent church; thus they spoke of the church of Antioch, of Corinth, of Rome; and yet they all formed but one church, the church of Christ, in which all were united in one faith. The universal or Catholic faith was regarded as the only correct body of belief; all conflicting opinions (the heresies) were condemned as errors.
The Sacred Books.—The sacred scripture of the Jews, the Old Testament, remained sacred for the Christians, but they had other sacred books which the church had brought into one structure (the New Testament). The four Gospels recount the life of Christ and the "good news" of salvation which he brought. The Acts of the Apostles describes how the gospel was disseminated in the world. The Epistles are the letters addressed by the apostles to the Christians of the first century. The Apocalypse (Revelation) is the revelation made through St. John to the seven churches of Asia. Many other pseudo-sacred books were current among the Christians, but the church has rejected all of these, and has termed them apocryphal.
