I've been meaning to post something about this, but I've found myself oddly without a Biblical position on this until now.
Think about it, Allah is the Pegan moon god (Satan).
Their book is based on the ramblings of Mohammed the murder, whose parents were supposedly slain by Christians and who was supposedly oppressed by the Jews.
The Koran is a book of death to anyone but those who worship their false god.
So the only real Biblical position one could take, is:
Matthew 5:43-48 - "You have heard that it was said, 'You shall love your neighbor and hate your enemy.' But I say to you, love your enemies, bless those who curse you, do good to those who hate you, and pray for those who spitefully use you and persecute you, that you may be sons of your Father in heaven; for He makes His sun rise on the evil and on the good, and sends rain on the just and on the unjust. For if you love those who love you, what reward have you? Do not even the tax collectors do the same? And if you greet your brethren only, what do you do more than others? Do not even the tax collectors do so? Therefore you shall be perfect, just as your Father in heaven is perfect."
It's my opinion, that as a Pastor, he should NOT BE THE ONE LEADING THE CHARGE... If a member of his congregation did it, that would be one thing (still wrong though), but for the Pastor to be doing it himself, shows a thorough lack of discernment.
