4:15 Nymphas. An inhabitant of Laodicea.
The church which is in his house, His in the Common Version; her in the Vatican MS, but the best authority renders it their house; i.e. the house of Nymphas and his family. In the first century no church building existed, and the Christians met in private houses. A portion, at least, of those in Laodicea met in the house of Nymphas, and are greeted as the church in their house (Revised Version). See also Ro 16:5 1Co 16:19 Phm 1:2.
4:15 Nymphas - Probably an eminent Christian at Laodicea.
4:10-18 Paul had differed with Barnabas, on the account of this Mark, yet he is not only reconciled, but recommends him to the churches; an example of a truly Christian and forgiving spirit. If men have been guilty of a fault, it must not always be remembered against them. We must forget as well as forgive. The apostle had comfort in the communion of saints and ministers. One is his fellow-servant, another his fellow-prisoner, and all his fellow-workers, working out their own salvation, and endeavouring to promote the salvation of others. The effectual, fervent prayer is the prevailing prayer, and availeth much. The smiles, flatteries, or frowns of the world, the spirit of error, or the working of self-love, leads many to a way of preaching and living which comes far short of fulfilling their ministry. But those who preach the same doctrine as Paul, and follow his example, may expect the Divine favour and blessing.
