Yes, the Pope said something which was interpreted as meaning the Prophet Muhammad's command to spread Islam by the sword must indeed be "evil or inhuman". Perhaps he should have chosen his words carefully. And he realised that and has expressed deep regret. Only God knows what was the Pope's intention in saying the offending words. Only God knows. Not you. Not me.
Sometimes, I am amused by the request or demand to "retract one's statement". This also happens in a Court of Law. A counsel challenges a witness to a fact which he knew was irrelevant to the case and would not have been admitted in any event. However, the purpose of putting the fact is merely to stain the credibility of the witness eg. on bad character. The witness's counsel then objects to the questioning made and the counsel retracts his question. By then, the whole courtroom would have heard the damaging fact and formed an opinion on the witness.
Demanding the Pope to "retract his statement" (as some leaders and countries have made) does not reverse the fact that he made the statements (offending or not). If somebody shouts at you in public saying that your parents are murderers or thieves, would his "retracting of his statement" change the fact that you have been hurt or that others have formed an opinion about you? I suppose, to some, they obtain comfort when the offending party retracts the offending statement. If it will comfort them, then the Pope should seriously humble himself and retract the statements for the peace of mankind. But then again, it is his personal decision to make. You and I cannot make the decision for him.
I am reminded of the following passages from James in the bible:-
7All kinds of animals, birds, reptiles and creatures of the sea are being tamed and have been tamed by man, 8but no man can tame the tongue. It is a restless evil, full of deadly poison. 9With the tongue we praise our Lord and Father, and with it we curse men, who have been made in God's likeness. 10Out of the same mouth come praise and cursing. My brothers, this should not be. 11Can both fresh water and salt[a] water flow from the same spring? 12My brothers, can a fig tree bear olives, or a grapevine bear figs? Neither can a salt spring produce fresh water. (James 3:7 - 12)
17But the wisdom that comes from heaven is first of all pure; then peace-loving, considerate, submissive, full of mercy and good fruit, impartial and sincere. 18Peacemakers who sow in peace raise a harvest of righteousness. (James 3:17 - 18)
Let us all, collectively, men of all religions, pray for peace and harmony amongst mankind. If indeed you believe that God created all men, then all of us belong to God and He has the right to deal with all of us according to His will. Each of us will have to account to God for our doings.
7 But when they persisted in asking Him, He straightened up, and said to them, "He who is without sin among you, let him be the first to throw a stone at her." (John 8:7)
