Here is an interesting take on the Mark of the Beast:
Tefillin are worn in obedience to the second part of the Shema (Deuteronomy 6:4f). They are a symbol of a commitment to Torah observance.
Because Tefillin are worn on the head, and the Mark is also worn on the head, essentially Lizorkin-Eyzenberg is saying that the Mark is anyone who has rejected obedience to God's commandments.
If correct, then in this age where the prevailing wisdom is that to faithfully follow the Torah's commandments is considered "legalism," then many Christians may be unwittingly bearing the Mark already.
