Christian critics of Islam have long been bringing up the false statement, asserting that Muslims are allowed to lie, be deceptive in order to bring non-Muslims to Islam. Let’s be clear, nowhere in Islam is there anything what these liars have stated. I will address this false claim soon, God willing.
Paul admits during his ministry, preaching his Paulinism (Christianity of today), he falsely acted in order to draw people to his faith. In the following passage he openly confesses that he used deception for conversion:
1 Corinthians 9:19-23 Though I am free and belong to no one, I have made myself a slave to everyone, to win as many as possible. To the Jews I became like a Jew, to win the Jews. To those under the law I became like one under the law (though I myself am not under the law), so as to win those under the law. To those not having the law I became like one not having the law (though I am not free from God’s law but am under Christ’s law), so as to win those not having the law. To the weak I became weak, to win the weak. I have become all things to all people so that by all possible means I might save some. I do it all for the sake of the gospel, that I may share with them in its blessings.
Paul is confessing in the above passage that, he acted as a Jew in order to convert them to his faith. He even acted as a pagan so that he can lure them to his religion. The above verse shows that Paul would go in great lengths to spread his religion by deception. Let’s see now what the experts have to say on the above passage.
Loyal D. Rue who is a Professor of religion and Philosophy at Luther college, comments on the passage, he writes:
“In the Christian tradition there is very early precedent for the use of deceptive means for evangelistic purposes. St. Paul himself makes a remarkable admission of his chameleon-like behaviour in the winning converts. Like the consummate used-car salesman, Paul pretends to share the concerns of his immediate audience in order to manipulate them into submitting to his Gospel: “Though I am free and belong to no one, I have made myself a slave to everyone, to win as many as possible. To the Jews I became like a Jew, to win the Jews. To those under the law I became like one under the law (though I myself am not under the law), so as to win those under the law. To those not having the law I became like one not having the law (though I am not free from God’s law but am under Christ’s law), so as to win those not having the law. To the weak I became weak, to win the weak. I have become all things to all people so that by all possible means I might save some.” 
In the Book “Shell Games: Studies in Scams, Frauds, and Deceits (1300-1650)” Richard Raiswell says that deception is endorsed in the Bible if it is for just cause:
“In his letter to the Corinthians, Paul describes how he deliberately masqueraded in false colours in order to advance the cause of the faith: ‘To the Jews I became as a Jew, that I might gain the Jews; to those who are under the law, as under the law, that I might gain them that are under the law.’ If the apostle can become all things to all men, then it would see that Scripture implicitly endorses deception when practiced in pursuit of a just cause. Perhaps most conclusively, though, God himself seems not have been above engaging in a little deception from time to time. To ruin Ahab, King of Israel, for instance, the Lord became a lying spirit in the mouth of Ahab’s prophets. Later, speaking through the person of Ezechiel to certain of the elders of Israel, God makes it clear that if the prophet appears to have been deceived in some matter, this deception is of divine origin. In the New Testament, Christ also appears on occasion to have been less than honest. When, after the resurrection, Peter and Cleopas set off for the town of Emmaus, they encountered Christ on the road; as they approached their destination, Luke records that Christ pretended to go further.” 
James Prince who is the author of the book “The True face of the Antichrist” also makes mention that Paul is a deceiver. I will remind the viewers that this individual is a Christian himself who believes in Jesus Christ, but he does not believe in Paul, according to him he is the “Antichrist”:
“Paul’s testimony proves his own hypocrisy here in 1 Corinthians, 9, 19-22…….…….. Again here I would trade the word save for trap in Paul’s case. Then Paul pretended to be the saviour after all this. I also believe that a person who is weak needs someone strong for support either physically or spiritually. Let me tell you too that neither Jesus nor his disciples became homosexuals to save homosexuals and neither prostitutes to save prostitutes. They didn’t become all to save everybody. This is totally abomination and hypocrisy. Paul, from his own writing, his own admission said that he was all to trap people. What wouldn’t the devil do to deceive? Jesus warned us though. See Matthew 24:4. “Jesus answered: Watch out that no one deceives you.” 
Even the early Church fathers understood this passage (1 Corinthians 9:19-22) that Christians are allowed to use deception for greater good. Christian theologian, Clement of Alexandria (born in the 150 – 215 A.D.), points out to Paul’s statement that lying is allowed in certain circumstances. Professor T. Brian Mooney writes about this in his book and says:
“Clement of Alexandria while praising the Christian who would not lie even in the face of torture or death makes an exception for ‘therapeutic’ lies, alluding to St. Paul’s dissimulations in Acts 16:3 and 1 Corinthians 9:20 (Clement of Alexandria, Stromata, 7.9.53).” 
Further evidence which shows Paul openly confessing to the Christian Corinthians that he used deception against them. The verse states:
Corinthians 12:16 Now granted, I have not burdened you; yet sly as I am, I took you in by deceit!
When one reads the above verse, it becomes even more evident that Paul used deception in many instances. Of-course Christian apologists in a desperate attempt to save Paul’s neck, they will say: “these words are not Paul’s but the words of the Corinthians who are accusing Paul of this”. Whatever way apologists want to put it, the verse is very clear that Paul confesses to using deception or the Christians Corinthians say that of Paul. If apologists don’t agree, saying it was the Corinthians accusing Paul of this, charging him with deception, either way Paul is a deceiver. Earliest Christians themselves didn’t find Paul to be truthful, so how can Christians of today try defend him, when the Corinthians charged Paul with deception?
The academic evidences presented shows that Paul indeed sanctioned lying. Paul not only deceived people, but also demonstrated to his Paulinism followers how to deceive humans. This kind of deception is very widespread. One only needs to look at third world countries and see for themselves, how missionaries deceive, con people out of their lives. So, next time Christian missionaries try use the argument that Islam allows lying (when that is NOT true), brothers/sisters just show them their Holy Paul used deception to convert people to his Paulinism.
