“Beloved, when I gave all diligence to write unto you of the common salvation . . .” (Jude 1:3)
The description of our salvation as “common” does not mean that salvation is “ordinary” or “normal,” but rather that salvation is available to anyone who wants it. The term is translated “unclean” several times in passages that speak of items that are accessible to everyone, rather than specialized foods or ceremonies available to just a few (Acts 11:8; Romans 14:14; etc.).
Right after Pentecost, the Jerusalem church experienced a quick growth in converts, many of whom were poor and needed practical help. The bond of the new church was so strong that “the multitude of them that believed were of one heart and of one soul: neither said any of them that ought of the things which he possessed was his own; but they had all things common” (Acts 4:32). That is the sense in which Jude speaks of a “common” salvation.
The salvation is available to all. “For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth” (Romans 1:16). None are excluded from the possibility of salvation—except those who refuse to believe what God has provided through the substitutionary death and resurrection of the Lord Jesus Christ (1 John 2:2).
But this salvation is also necessary for all. “Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved” (Acts 4:12). It has become popular today to couch the gospel message in moderate terms, making the message appear optional or a “personal” belief system. No, it is the only salvation, even if it is “common.” “Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me” (John 14:6). HMM III
