John gives one of the sharpest commands in the New Testament. “If anyone comes to you and does not bring this teaching, do not receive him into your home, and do not greet him” (2 John 10, CSB). Modern ears often hear that as unloving. Harsh. Suspicious. Yet Mark Penrith reminded us, “This is not rudeness. It is protection.” John is not forbidding kindness to unbelievers. He is forbidding support for false teachers who distort the person and work of Christ.
In the early church, hospitality meant far more than sharing a meal. Welcoming a travelling teacher meant endorsing him. Funding him. Helping spread his message. Mark explained, “To receive a teacher was to endorse him. To fund him. To say, This man speaks for God.” John says believers must not do that for deceivers. Why? Because truth protects the flock. A church that loves Christ and His people cannot open the door to teaching that destroys souls.
Fathers understand this instinctively. You lock your doors at night because you love your family. You place boundaries around your home because protection is an act of love. Mark said, “Love for the flock requires a closed door to wolves.” Behold the wisdom here. The goal is not suspicion toward everyone. The goal is protection from spiritual harm. Churches guard doctrine for the same reason shepherds guard sheep. Love refuses to stand idle while danger enters the fold.
John adds this warning, “For the one who greets him shares in his evil works” (2 John 11, CSB). That should sober us. Christians must think carefully about what they promote. What they recommend. What they celebrate publicly. Mark urged believers to “test before you welcome.” Before sharing content online or recommending a preacher, pause and evaluate carefully. Does this teacher faithfully proclaim the biblical Christ? Love requires discernment. Wisdom is part of holiness.
Parents should also explain boundaries to their children. Some influences help us follow Christ. Others slowly pull hearts away from Him. Mark said, “Our closed door to heresy is not hate. It is loving protection of our flock.” That principle belongs in both church life and family life. True love protects what matters most.
Prayer: Father, give us wisdom and discernment. Help us guard our homes and churches with courage, humility, and love for the truth of Christ. Amen.
