The book of Acts and the Epistles reflect continuing involvement of Christians with the institutions of Jewish worship. However, with the Gentile mission and increasing separation from the temple and synagogues, the churches had to develop their own forms of common worship. Even Jewish Christians came under increasing pressure as persistent evangelism aroused the hostility of the ecclesiastical authorities.
The Temple and the Early Church
The temple figures prominently in the worship of the infant church. After the Ascension, the disciples were continually in the temple praising and blessing God (Luke 24:51–53). Part of the fellowship of the Jerusalem church was daily attendance in the temple (Acts 2:46). Peter and John healed the lame man on their way to the temple at the hour of prayer (Acts 3:1–10). Like Jesus, the apostles stood in the temple and taught the people (Acts 5:25). Later, Paul was anxious to be in Jerusalem for the day of Pentecost (Acts 20:16). One of his first acts on reaching the city was to make his way to the temple and undergo ritual purification (Acts 21:23–26). When arrested and accused, Paul protested strongly that he had not offended in any way against either the law or the temple. The witness of Stephen shows that the early church had a strong sense of the transitoriness of the earthly temple (Acts 7:47–50). The problem of Judaizing was important at this very point, for those who attached greater importance to the temple naturally wanted the Gentiles to become Jews so they could worship there. The church, led by Stephen and Paul, came to see that this was neither possible nor right. Nevertheless, so long as the temple remained, it was for Jewish Christians a proper center of the true, divine worship, which is in faith, obedience, sincerity, and truth.
The Synagogue and the Early Church
The Christian’s relationship to the synagogue was equally strong, though the opportunity of exposition soon made the synagogue a place of contention and separation. Stephen seems to have engaged in synagogue evangelism (Acts 6:9–10). Paul made the synagogue the starting point of his missionary work in the various cities (Acts 13). He preached in the synagogues at Pisidian Antioch and Iconium and found a house of prayer at Philippi. It was Paul’s custom to attend the synagogue, and he reasoned for three Sabbaths in the synagogue at Thessalonica (Acts 17:1–2). As late as Acts 28:16 he called the Jewish leaders of Rome together—his detention probably prevented his worshiping at the synagogue—and sought to persuade them of the verity of the gospel. In most of the Pauline churches, the first converts came from the synagogues, though in no instance did a whole synagogue become a Christian congregation.
The division that took place in the synagogues through the preaching of the gospel meant that Christians were forced to hold their own gatherings. They had been prepared for this by the special times of fellowship the first disciples had enjoyed with their Lord, whether formally at meals or more informally. The first church in Jerusalem met together in the upper room for prayer (Acts 1:14; 4:31; 12:12). The breaking of bread, whether in the form of common meals, the Lord’s Supper, or both, played some part in the movement toward the church’s independent worship. Outside Jerusalem Paul (and Barnabas) apparently took steps to bring believers together for their own gatherings, which in some instances might have been supplementary to synagogue services, though there was a definite separation at Ephesus (Acts 19:9). The comparative ease with which synagogues could be formed, the pattern of worship already provided, and the conversion of leading members (cf. Crispus, the ruler of the synagogue at Corinth, Acts 18:8) helped to make the formation of Christian congregations a smooth and simple process. Believers probably met in houses, due to the absence of church buildings, and so one reads of house churches (cf. Philem. 2). The apostles made provision for the supervision of the new assemblies (Acts 14:22). Somewhat after the pattern of the synagogue, the two chief ministers were the elder (bishop) and deacon, though it is perhaps a mistake to see too close an assimilation to synagogical forms.
What form of worship was pursued in the Christian assemblies? The New Testament gives little detailed information. From the first chapters of Acts, it may be gathered that prayer and the breaking of bread were primary. The only other detailed sources are in Acts 20 and 1 Corinthians 11 and 14. Acts 20:7 records a meeting on the first day of the week at which the disciples broke bread and Paul preached; the meeting seems to have been in the evening. First Corinthians 11 also speaks of a common meal, which is plainly the Lord’s Supper (1 Cor. 11:23–34), though probably in combination with an ordinary supper. First Corinthians 14 mentions a gathering at which members might contribute a psalm, a doctrine, a tongue, a revelation, or an interpretation, though with an emphasis on edifying and order. The injunction in 1 Corinthians 16:2 is perhaps a further hint that these assemblies were held on the first day of the week. Whether Corinth was typical cannot be decided, nor indeed whether the procedure in 1 Corinthians 14 is supplementary to more organized worship, such as at the Lord’s Supper. Perhaps the Corinthian emphasis on tongues carried with it a more-than-customary drive for freedom.
The sources do not indicate that a recognized structure had emerged at this period. Nevertheless, even at Corinth the constituent features of worship—prayer, praise, exposition and perhaps reading of the Scriptures, and the Lord’s Supper—are evident. The materials of the liturgy are also present. The Psalms would be the Old Testament Psalter, and readings involved a fixed form of words. Paul gives a simple order for the Lord’s Supper. Part of the general content of prayer is suggested in 1 Timothy 2:1–3. The prayer of Acts 4:24, though extemporaneous, uses liturgical phrases obviously drawn from the Old Testament. Even the sermons recorded in Acts are not without patent similarities of wording and structure. Since the primitive church is heir to the rich tradition of the Old Testament and Judaism, it would be strange if this were not so. The new spirit and power lie in the new understanding of the old forms, the fashioning of new forms out of the old, rather than in formlessness.
Personal Devotion and Piety of Early Christians
Individual piety finds no less expression in the life and teaching of the apostles than in that of the Lord. Paul is a good example. He practices (1 Thess. 2:1) and urges (1 Thess. 5:17) unceasing prayer. He calls for prayer in support of his ministry (Eph. 6:18). In many passages, he indicates the content of his own prayers, which in the Epistles at least are largely intercessory in character (Phil. 1:4–11; Col. 1:9–12), though a passage like Philippians 3:8–11 becomes almost a prayer of aspiration, and his first Christian prayer (Acts 9:11) was almost certainly a prayer for forgiveness and enlightenment. The indication of content is even more extended in Ephesians 3:14–21, which seems to have been dictated by the apostle quite literally on his knees in the gesture of individual prayer (Dan. 6:10). This prayer of petition characteristically moves to a doxological climax that expresses the confidence of faith and that sees in all God’s work fulfillment of the first request of the Lord’s Prayer. Steeped as he is in Old Testament and Jewish forms, Paul adopts quite naturally a liturgical language that is a free adaptation of existing phrases. The intensity of his faith and devotion, allied to extensive biblical knowledge, produces a perfect blend of dignity and fervor.
In addition to prayer, Paul commands a diligent study of the Scriptures, whether by reading or by committing to memory (cf. 2 Tim. 3:15–17; Eph. 6:17). He also calls for a life of self-discipline, which may include celibacy if this is the divine command (1 Cor. 7:1–8), but which certainly includes a subjection of the body for the sake of better service (1 Cor. 9:24). The discipline of fasting is not neglected (2 Cor. 11:27). Thanksgiving is also to be the constant attitude and exercise of the believer (1 Thess. 5:18). The grave and sober conduct expected of bishops and deacons (1 Tim. 3) do not specify a personal exercise of piety, but it is implied. Timothy, as a man of God, is exhorted to pursue godliness (1 Tim. 6:11). While the worship of the individual merges into that of the fellowship, and also into general uprightness of life and conduct, the personal exercise of religion is an important aspect of worship in the New Testament.
