Solus Christus – Through Christ alone. This marks our 4th cult-proofing slogan. And it is just as essential as the others. It is in Scripture alone, and by its sole authority, that we learn that the malady of the sinful rebellion of lost humanity against God has a remedy which is ours by God’s free gift of grace alone, obtained through faith alone, because of the substitutionary death of Jesus Christ on Calvary – alone. Or, as we read in Acts 4:11-12 “This Jesus is the stone that was rejected by you, the builders, which has become the cornerstone. 12 And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved.”
Beloved, once again, EVERY false belief system or cult errs on this point. Each and every one of them posits SOME kind of addition to the work of Jesus at Calvary as essential for our salvation. But, “it is impossible for the blood of bulls and goats to take away sins.” (Hebrews 10:4) No sacrifice can do it. And, “He is the radiance of the glory of God and the exact imprint of his nature, and he upholds the universe by the word of his power. After making purification for sins, he sat down at the right hand of the Majesty on high.” (Hebrews 1:3) These things He has done alone. There is nothing to be added. Concepts like Purgatory or personal acts of penance rob Jesus of His mediatorial glory. If His infinitely righteous blood shed in death for my sin is not sufficient to God, what hope do any of us have? What can possibly be of more effect? Who can possibly be more worthy? “For there is one God, and there is ONE mediator between God and men, the man Christ Jesus, 6 who gave himself as a ransom for all, which is the testimony given at the proper time. 7 For this I was appointed a preacher and an apostle (I am telling the truth, I am not lying), a teacher of the Gentiles in faith and truth.” (1 Timothy 2:5–7, emphasis mine)
No other mediator. No other means. No other sacrifice. No other works of obedience. No other anything. We are saved – through the mediating work of Jesus Christ and Him alone. His sole obedience to the Father on our behalf – to give us a righteous history. His sole death on the cross enduring our guilt and shame so that we might have an expunged sentence. No thing more is due – nor could we pay it if we still owed the smallest portion of it. Christ, and Christ alone – saves. He is the Savior of lost people.
