Wow. I bet you have problems getting out of bed in the morning.
Let me guess:
1) Makeup is also the "mark of the beast?"
2) Dancing invites the devil into your body?
3) Shaving your beard is defiling God's body?
4) Driving a car is a blasphemous, unnatural, unGodly act?
5) Women should walk behind their men?
6) You will go to Heaven. All those who skated to Hell?
Teach them. LOL.
It was offered as such.
Method and medium do not matter.
As a matter of fact, the simple act of being asked to accept and agreeing is enough.
No physical act or mark is necessary.
Have a Nice Day.
