Acts 10:15 records a divine command that overturned a long-held Jewish food rule: what God has declared clean is not to be treated as unclean. The verse is the second half of a vision God gave the apostle Peter, and it settles a question that had quietly divided the early church, namely whether Gentiles could be welcomed into the faith without first living under Jewish dietary laws.
A voice came to him again the second time, “What God has cleansed, you must not call unclean.”

What Acts 10:15 Means
The verse has two parts that work together. The first is the word “cleansed,” which describes an action God has already taken. It means God has set something apart as acceptable, so that it no longer carries the stain of impurity. The second is the instruction “you must not call unclean,” which tells Peter how to respond. He is not to keep labeling as defiled what God has declared fit. The verse is less about food than about the authority of God to decide who and what is acceptable, and the human duty to recognize that decision.
It is worth being clear about what the verse does not say. It does not announce that every moral failing is now acceptable, and it does not describe a general rule for all of life. Its immediate subject is ritual purity around food and contact with non-Jewish people. The principle beneath it, that God alone defines what is holy and clean, is wider, but the verse itself speaks to one specific barrier that God was removing.
The Context of Acts 10:15
The book of Acts was written by Luke, the companion of Paul, and addressed to a man named Theophilus. It traces how the message about Jesus spread from Jerusalem outward, and chapter 10 marks a turning point, because it is the account of the first Gentile household to receive the Holy Spirit through the preaching of the gospel. Peter, a devout Jew, has just been given a vision of animals that the law forbade eating, and a voice tells him three times to kill and eat.
The verses just before and after explain why the verse matters. Peter’s reply, “Not so, Lord,” shows how deeply his upbringing shaped him. Immediately afterward, messengers from a Roman centurion named Cornelius arrive at the door, and Peter goes with them to a Gentile home. The vision was not only about meals. It prepared Peter to cross a social and religious boundary that his tradition had taught him to keep, and to see that God was extending grace to people he had once regarded as outside the covenant.

A Short Prayer From Acts 10:15
Lord, you see the places in my heart where I have drawn lines you never drew. Show me the people and habits I have labeled as beyond your grace, and soften my judgments with the knowledge of your mercy. Help me trust your declarations more than my old instincts. Make me willing to receive what you have made clean, and to speak of it with the same generosity you have shown me. Amen.
