3 Beloved, while I was very diligent to write to you concerning our common salvation, I found it necessary to write to you exhorting you to contend earnestly for the faith which was once for all delivered to the saints. 4 For certain men have crept in unnoticed, who long ago were marked out for this condemnation, ungodly men, who turn the grace of our God into lewdness and deny the only Lord God and our Lord Jesus Christ.” (Jude 3–4, NKJV)
Jude was eager to write to faithful brethren about “our common salvation.” But, an even more pressing need arose that required his immediate attention. His epistle gives a stern warning and a strong indictment of false teachers who had slipped in among them unnoticed. Their teaching was corrupting the grace of God, offering sinful abandon rather than the self-control of holiness. This was nothing less than a denial of God and our Lord Jesus Christ (v. 4). Please note, there is a common salvation and a singular faith that we must contend for and from which we must not deviate. Just as there is only one way of salvation, there is only one faith (Acts 4:12; Ephesians 4:5). The ecumenical movement is a direct assault on both of these gospel principles. Unless we contend (struggle intensely) for the gospel that was fully and finally delivered to the world by the apostles and prophets of Jesus, we have already abandoned our common salvation for the whims and impulses of men. The enemies of truth are afoot. Let us “fight the good fight of faith” and “lay hold on eternal life” (1 Timothy 6:12).
