Heh! Maybe so, but GreyFriar's mention of "1st Century" was in reference to a small group called "First Century Christianity" that met at our church from 1989 to 2006. We were trying to re-discover what a meeting of Christians was like before all the church councils and doctrines and dogmas and such that originated after AD 100. Among many other topics, we discussed John's Revelation and what it would mean to us if we had just received a copy of it.
oh, I thought you guys were joking around “didn’t we discuss this before, in the 1st century”!
I guess it depends on where you would have been. The Syrian Christians (who i'm guessing were a large chunk of the Christian world flat out rejected it. Even today the Eastern Orthodox do not read Revelation in the Divine Liturgy. in fact many of the Early Christians rejected it again as it seemed too closely tied to Gnostics and Montanists
Ireneus and Origen did not include it in their canons
Clement of Alexandria in 200 also did not include it as canon.
So, if in 100 you received this book, most like you would have rejected it.
