The life and worship of the first converts. The converts were still earnest Jews, attending the services in the Temple daily (Acts 2:46), but they already formed a Church within a Church: for (1) they continued stedfastly in the Apostles' doctrine (Acts 2:42), i.e. they no longer regarded the chief priests, scribes, and Pharisees as their accredited teachers, but rather the Apostles. Thus the breach with Judaism had already begun in principle. (2) They continued stedfastly in the Apostles' fellowship. (3) They continued stedfastly in the breaking of bread, i.e. in celebrating the sacrament of the Lord's Supper, or Holy Communion. At first the Lord's Supper was celebrated daily (Acts 2:46), but afterwards every Lord's Day at least (Acts 20:7). (4) They continued stedfastly in the prayers, i.e. in the prayers offered at the celebration of the Lord's Supper, and at the other services of the Church (so the RV). The AV, however, translates 'in prayers,' which would include private prayers also.
