In the Gospel this Sunday (Matthew 18:1-20), Jesus teaches us what great lengths we are to go to rescue our brothers and sisters from falling away from the faith. As Christians, we will always struggle against temptation and fall into sin while we remain in our sinful flesh and live in this sinful world. But as long as we continue to hear God's Word and receive the Sacrament frequently, the Holy Spirit will continue to work repentance in us and preserve us with Christ's forgiveness unto life everlasting.
Sadly, however, many believers, when they fall into sin, instead wander away from Christ and His Church and eventually become lost (i.e., become an unbeliever). As our Lord Himself taught us in the Parable of the Sower (Matt. 13), there are many things that can choke out the Word of God and cause Christians to depart from the faith. Whether it is because of their own stubbornness or because of the allure of the riches and pleasures of this world, or whether it is because Satan has seduced them into false belief, despair, or some other great shame or vice, for various reasons believers often go astray from the Church and never return.
As members of the Church, the Body of Christ, it should pain us whenever this happens. For we are members of one another (Eph. 4:25). Whenever a member of the Church, especially a member of this congregation, falls into sin and departs from the faith, God wants us to grieve as if we had just lost an arm or a leg. Although I have never experienced such bodily dismemberment, I can only imagine it is extremely painful. When one member of the body suffers, the entire body suffers. And not only is it painful for us, but it is painful most of all for Christ, who is the Head of the Body, the Church (Col. 1:18). The LORD grieves every single time a Christian falls away or a sinner refuses to repent and dies in his unbelief. As we will hear in our first reading Sunday, “‘As I live,’ says the Lord GOD, ‘I have no pleasure in the death of the wicked, but that the wicked turn from his way and live'” (Ezek. 33:11).
But God does more than grieve whenever one of His children goes astray. He takes action. Christ our Savior does everything He can to go after His straying sheep, like the man who left the ninety-nine to go to the mountains to seek after that one sheep who was wandering away (Matt. 18:12). And so Christ wants us to do more than simply grieve over those who are wandering away from the Church. He calls us to take action, just like Him. As members of the Body of Christ, it is our responsibility to do something whenever one of us is in danger of apostasy. We are obligated not only by Christ's command, but also by our love for one another. And to aid us in this work, Christ gives us the most powerful means by which we can evangelically chase down our brothers and sisters who are in danger of falling away: the Office of the Keys.
This Sunday, we will learn from our Lord not only what the Office of the Keys is, but also how He wants us to use these heavenly keys to loose (and bind) His forgiveness to those in need, for "it is not the will of your Father who is in heaven that one of these little ones should perish” (Matt. 18:14).
