The Eighth Sunday after Trinity

The Eighth Sunday after Trinity – July 21, 2024

Psalm 48; Jeremiah 23:16-29; Romans 8:12-17

St. Matthew 7:15-23

In the Name of the Father, and of the + Son, and of the Holy Spirit. Amen.

The phrase, “a wolf in sheep’s clothing” is often used to describe someone or something that outwardly appears good, helpful, pleasant, or beneficial, but turns out to be harmful, dangerous, painful, or evil. Such a common use of the phrase is good. It reminds us that Western society is founded on the words of Scripture. But the common use of this phrase is lacking the intensity with which our Lord first spoke it. The result of listening to these false prophets is not bad feelings, sadness, or even death. It is eternal death, condemnation in hell.

Pure doctrine is a matter of eternal life and eternal death. Just before the Gospel text for today, our Lord says, “Enter by the narrow gate; for wide is the gate and broad is the way that leads to destruction, and there are many who go in by it. Because narrow is the gate and difficult is the way which leads to life, and there are few who find it.”[1] This sets the stakes for dealing with wolves in sheep’s clothing.

When you stand before Jesus Christ on the final day, it will be your doctrine that is judged. You cannot blame your misunderstandings or false doctrines on your parents or pastors.[2] Those given the office of preacher will be judged more harshly for they are responsible for communicating the Word of God but that does not excuse the hearer.[3] You must stand and confess your faith on your own.[4] It is your responsibility to maintain the true faith once delivered to the saints.[5]

Pure doctrine is not just facts or words to be memorized. Pure doctrine is to come to know the God who created, redeemed, and sanctified you most intimately. Learning pure doctrine is drawing near to the God who took on your flesh to die for your sins. Knowing the Word of God is knowing that Word that is the Way, the Truth, and the Life.

For this reason, it is necessary that all Christians know the doctrines of Scripture. It is necessary that all Christians be able to evaluate, or judge, the doctrine of your preacher. How do you do that? By comparing his doctrine and life to the Word of God. The fruits of the good tree and the evil tree are both the teachings and actions of the prophets. Does he teach the Word of God? Are his teachings in line with the teachings of Scripture? Or does he tell you what you want to hear?[6] Does he tell you what is comfortable instead of what God has stated? Does he let sin go unjudged or does he call you to repentance? Does he lead a life that brings honor to the office of Christ? Is he pious and living outwardly such that he is above reproach? Or does he preach against adultery while committing sexual acts with someone other than his wife?

Now, none of this is to be judged by how you think or feel, what is comfortable or novel. It is to be judged by the Word of God.[7] For this reason, it is necessary that the sheep know the voice of the Good Shepherd; that you know the Scriptures for it is they that testify of Christ.[8] Do you rely on “what you’ve always thought,” or “what you’ve always been told”? Or do you search the Scriptures, seeking wisdom and strength?[9]

This is a difficult task. It is an essential task, but it is a difficult one. It is made even more difficult because the false prophets, the wolves, wear sheep’s clothing.[10] These wolves do not wear undershepherd’s clothing, but they hide among the sheep. What does that mean? It means that the false prophet will often hide his false teachings and his wicked life as being common, being “just the way things are done.” He might claim, “well, the Scriptures say that only men are to teach in the church, but that isn’t true here; we’ve always had women read the lessons.”

Such false doctrine is most obvious in the mainline denominations today.[11] Look at how quickly denominations have capitulated not only to women’s ordination, but to accepting, blessing, and upholding homosexuality. A hundred years ago, very few in the church would’ve dreamed of talking about such degeneracy, let alone blessing it. A hundred years before that, and it would be common for preachers to speak of strict legal punishment for such sins because they harm our society, our families, and our children, even if we, ourselves, don’t participate.

“But pastor,” you might say, “are you saying that only Lutherans go to heaven?” By no means! There are Christians in every denomination who confesses the doctrines of Scripture.[12] The Church is not constituted by human organizations. The Church is wherever Christians gather to hear the Word of God taught in its truth and purity and to receive the Holy Sacraments rightly administered.[13] However, every false doctrine they believe is like a dead bug in your soup. Can you survive eating one dead bug? Probably. What about two? Three? Each false doctrine believed by a denomination adds to the filth of their teaching until the whole soup is ruined. Jesus said, “a little leaven leavens the whole lump.”[14]

“But pastor,” you might say again, “what if you are in one of those denominations (let’s say, the Methodists) but you don’t believe that false stuff. What then?” Thanks be to God you do not believe the false doctrines of the Methodists, but I would ask why you are still in fellowship with them? To be a member of a congregation is like being married to it.[15] If you are publicly married to one congregation but claim to believe differently, then you are secretly in bed with someone else, some other church. Make it right by joining yourself to the Church which teaching the purity of God’s Word.

What then are you to do, or what is a congregation to do, should you find yourself being led by a wolf in sheep’s clothing, a false prophet who is teaching evil doctrine or living a wicked life? The first thing to do is talk to him.[16] Call him to repentance. Make sure that in doing so, you are able to show him from the Scriptures where his error lies. Make sure it isn’t something that you just don’t like or are unhappy with. Which commandments is he breaking? Which doctrine is he violating? Where in Scripture is he wrong?

If he repents of his false doctrine, thanks be to God! You have won your brother from the fires of hell. Depending on the severity of the false doctrine or the manner in which it was taught, it is then incumbent upon him to publicly repent and teach the proper doctrine.

If he repents of wicked living, the matter is a bit more difficult. Was his sin something that disqualifies him from the Office of the Holy Ministry? If so, then the fruits of his repentance is to resign. If his sin was not to that degree, then again, rejoice for you have won your brother’s soul from hellfire.

If you show your pastor where he has clearly erred – in doctrine or life – and he refuses to repent, then take it to the elders of the congregation and possibly involve the Circuit Visitor. If he still refuses to repent, then it is necessary that the congregation remove him from the Office. This should never be taken lightly, nor should it be the goal of calling the pastor to repentance. Just as the goal of excommunication is the salvation of souls, so too the removal of pastors is for the repentance of sins.

How do you arm yourself to judge the doctrine of your pastor? Immerse yourself in the teachings of Scripture. Too daunting? Begin with the Small Catechism. It is the summary of all doctrine necessary for salvation. Begin there and with reading God’s Word. Read the Bible from beginning to end. Start with the Gospels, then the histories of the Old Testament, then the Epistles, and finally the prophets. Pray the Psalms and the Proverbs. Do this over and over again and you will be equipped with everything to need to judge doctrine.

“We have thought on Your steadfast love, O God, in the midst of Your temple. As Your name, O God, so Your praise reaches to the ends of the earth. Your right hand is filed with righteousness.”[17]

In T Jesus’ name. Amen.
