Cutting of the head is effective, and crucifixion is guaranteed painul.
Dr. Reagan’s paper includes these comments on beheading:
“... the Bible says the Antichrist will behead those who resist him, and Richardson spends an entire chapter emphasizing that execution by beheading is one of the cardinal characteristics of Islam...
“... The point about beheading is flimsy evidence at best. Beheading is not a unique characteristic of Islam. It was one of the stellar characteristics of the French Revolution, and is just the type of horror the Antichrist would institute, regardless of his nationality or religion.”

An Evaluation of the Muslim Antichrist Theory
