If we speak where the bible speaks and remain silent where the bible is silent, it is self evident that certain things will remain the same and some things will change. The question is whether or not we have the courage to change our life to fit God’s will, or do we attempt to change God’s will to fit our lives?
If we go by the new testament, without adding or subtracting from it, all will obey the gospel of Christ. The gospel is the death, burial, and resurrection of Jesus Christ (1 Cor 15:1-4). In order to obey the gospel one first must hear the gospel, for faith comes by hearing the Word of God (Rom 10:17). If we believe what we have heard from the heart and confess such with our mouth (Rom 10:9,10); If we repent and are baptized for the remission of sins (Acts 2:38); Then are we added by Jesus Christ to the One church which he paid for with His own blood (Acts 2:47 f; Acts 20:28).
The name of this church bears the Lord’s name (Acts 4:12): (e.g. church of Christ (Rom 16:16); church of God (2 Cor 1:1); church of the firstborn (Heb 12:23). The doctrine of this one church would be free from the traditions and doctrines and commandments of men (2 Thess 2:15). This one church would teach only the doctrine of Christ, which is the apostolic doctrine, which is the doctrine of God (2 Jn 9 ff; Acts 2:42; Jn 7:16,17).
This one church would worship God in spirit and in truth (Jn 4:23,24). This means the church would come together each Lord’s day to partake of the Lord’s supper and to give of its means (Acts 20:7 ff; 1 Cor 16:1,2; 2 Cor 9:6,7). The church would sing with their voices without the accompaniment of instrumental music (Eph 5:19 f; Col 3:16). There would be qualified elders and deacons in every church (Acts 14:23). Preachers would preach sound doctrine in and out of season (2 Tim 4:2-5). Faithful men would be teachers, following the traditions of the apostles (2 Tim 2:2). Faithful women would remain silent each time the church assembled (1 Cor 14:33-40).
The church would be ruled by it’s elders and not the elders of other congregations. The church would be sufficient to instruct its members, to assist the needy saints, and to do the work of the church without the aid of man-made institutions (Eph 4:11,12).
If we only spoke the oracles, the very words of God, the church would be united in truth (1 Pet 4:11). Paul commanded the churches to: “Now I beseech you, brethren, by the name of our Lord Jesus Christ, that you all speak the same thing, and that there be no divisions among you; but that you be perfectly joined together in the same mind and in the same judgment” (1 Cor 1:10). How can we all speak the same thing when we are following the ever changing doctrines of men? Only the doctrine of Christ remains the same in and out of season. The commandments of men turn us from the truth, not to the truth (Tit 1:14).
If we didn’t go beyond that which was written there would be no more church supported orphanages, colleges, or benevolent societies ( 1 Cor 4:6). There would be no more special collections separate and apart of what was commanded in 1 Corinthians 16. There would be no more church supported banquets, parties, leisure trips, camps, entertainment, etc.
Once we go down the road that a little error never hurt anyone; Once we start following the false doctrine of (the bible didn’t say not to); Once we stop adhering to God’s Word for all of our authority (Col 3:17), the church we attend will no longer be the church which Christ built, but will be the church in name only.
