"Indiana Jones" was popular at the time ( given the high birth rates, and Christian era love ), as well as, Bondage, Discipline, Dominance, Submission, Sadism, Masochism, and Goth, was also the norm. The problem with todays society in some cases, these things work out well.
"We gotta whip the devil out of you Jim"
"Tamed horses"
"That is some good, paddling"
Speaking of which, whipping, was and is still the most popular usage, of punishment in many nations around the world. From policing in first world nations, to correcting small children in third world nations. I can still remember those days, when we wanted to go for the sword, or the long-rang weapon, but then I remembered god, and Dracula ( the devil ) flew away, from my body in that instant.
Also a really, really, really, really, heavy whip, that is strong enough, can cut through, meat, and break bones, based on the persons own strength. It can be a really deadly weapon. in CV the whip is also blessed, and the user is considered a saint, in the matter. Yeah we gotta whip the devils out of mother earth.
Also think about it. CV logic takes place ( gets its mojojo from ) in the dark ages, the black plague, the little ice age, and so forth. What was it like back then in the post Roman empire being ruled by Bishops, Priests, and the Roman Catholic Church itself. Till this day, the Pope had said "Europe is rampid, with a veil of Sin" ( something like that ). Chances are they used whips, alot.
