“Happy is he that condemns not himself in that thing which he allows,” wrote Paul (Rom. 14:22). Liberals and perverters of truth, practicing some things “contrary to sound doctrine,” must exercise care that their inconsistencies are not too obvious to the public. Their preaching must be geared to their practice, not their practice to their preaching!
Some liberal minded brethren never preach on instrumental music in the worship. The reason being, they say, such practice is not mentioned in the Bible. They support religious activities for which there is not one verse of scripture to support them and they obviously know it. Furthermore, they know instrumental music in worship parallels such practice. They believe in one church sponsoring a work for which all churches are equally responsible. However, let them produce a scripture authorizing a sponsoring church! They believe that churches may monetarily subsidize human organizations to do the work of the church. However, let them produce a passage of scripture to authorize churches of Christ to to do so. They know the scripture makes the difference, and they also know their practice places them “in the middle”.
Any departure from the truth, though it may not be specifically named in the word of God, must be condemned. Paul shows the Ephesian elders that some from among themselves would arise “speaking perverse things” to draw away disciples (Acts 20:30). Do those “perverse” things have to be named before I can preach on them? There is only one gospel but many perverters of it (Gal. 1:6-12). The perversion of truth does not have to be specified in the scripture for one to preach against it! The gainsayers of truth must be stopped – they teach things which they ought not (Tit. 1:9-11). Paul told Timothy to charge some “that they teach no other doctrine” (1 Tim. 1:3). Does that false doctrine have to be named in the scriptures before I can rightfully preach against it? There are some things “contrary to sound doctrine” (1 Tim. 1:10) which are not specifically named in the scriptures – instrumental music in worship being one of them! Sins in the “such like” category must be condemned as well as the ones specified (Gal. 5:21). False teachers (2 Pet. 2:1) lead men away with error (2 Pet. 3:17). Instrumental music in worship is unauthorized and must be preached against, even if inconsistent preachers preach to the contrary.
