Not that being Catholic is relevant to this subject, and I have NO clue what Catholics of any stripes believe, and it does not matter what your http: site claims. Those that receive that 'mark' do so willingly, they do not know what the mark is.... now if a supernatural being shows upon this earth how would you know who that entity was. The 'mark' is about counting over a very long period of time..... how many know how to count that number???
The 'mark' is accepted because of lack of knowledge as to what literally the 'mark' is, and who will willingly accept and receive it. It is what you believe and who you believe, not a literal object that is visible.
While i am also not Catholic, i do know that there is little to no difference between Catholic eschatology and basic Protestant eschatology. The only real difference is that Dispensational Premillenialist thought is almost an exclusive Protestant teaching, and is to the best of my knowledge, never taught in the Catholic Church.
i find it most curious that if the poster JosephJames is the Catholic Priest who wrote this blog article, why on earth would he publish doctrinal teaching that is FAR outside the tradition of the Catholic Church?
Something is just a bit off here.
