And here is my message to you: "Torture of prisoners is an obvious sin which no Christian should ever support." In case you think otherwise, here are the Scriptures which make this fact absolutely clear. I am quoting from the three Bible versions which are most favored by Conservative Protestant Christians: The the King James Version (KJV), the New International Version (NIV), and the New American Standard Version (NASB). All of these Bible quotations are provided by http://biblegateway.com, a long-established trusted Christian source.
First, I cite Matthew 7:12, from Jesus' "Sermon On The Mount." In this Scripture, Jesus teaches us that all of "the Law and the Prophets" is summarized in this one verse. Please read it carefully, and then try to see how this Scripture permits torture of prisoners:
So in everything, do to others what you would have them do to you, for this sums up the Law and the Prophets. (NIV)
In everything, therefore, treat people the same way you want them to treat you, for this is the Law and the Prophets. (NASB)
Next, I cite Galatians 5:14, where the Apostle Paul, inspired by the Holy Spirit, is writing to the first-century Christians in Galatia (now part of Turkey.)
For all the law is fulfilled in one word, even in this; Thou shalt love thy neighbour as thyself. (KJV)
The entire law is summed up in a single command: "Love your neighbor as yourself." (NIV)
For the whole Law is fulfilled in one word, in the statement, "YOU SHALL LOVE YOUR NEIGHBOR AS YOURSELF." (NASB)
But some people may say, "Yes, I know it is a sin to torture prisoners. But maybe it is necessary to accomplish the greater good of saving innocent lives."
In response to this, I cite First Corinthians 10:13, where Paul is filled with the Holy Spirit, writing to the Christians in Corinth. He teaches us that God will always give us a way to accomplish any good purpose without the need to sin.
