Revelation 1:10. I was in the Spirit on the Lord’s day, and heard behind me a great voice, as of a trumpet..
John did not pen he was at an Easter Sunday mass... The Lord’s day is a time signature, and lasts a thousand years.. the return of Christ is day one of His reign.
John was brought forth in the Spirit to reveal what would be and what had been. Nero was a tin horn in comparison to what and who is coming... the beast is likened to a whole new world and it’s intertwined religious government system.. Like the Babylonian kingdom, then Persians, then Greek/Roman then the ‘iron’/clay mix.. Iron and clay do not mix.. and will last for a short season...
Indeed John did not pen he was at an Easter Sunday mass, which would be another example of Catholic abuse of Scripture, compelling it to service Rome, reading into it what it does not say, and contradicting what it does say.
I was in the Spirit on the Lord’s day, and heard behind me a great voice, as of a trumpet, Saying, I am Alpha and Omega, the first and the last: and, What thou seest, write in a book, and send it unto the seven churches which are in Asia; unto Ephesus, and unto Smyrna, and unto Pergamos, and unto Thyatira, and unto Sardis, and unto Philadelphia, and unto Laodicea. (Revelation 1:10-11)
There is nothing here about John being at Easter Sunday mass - which is an unscriptural contrivance of the Lord's supper - and on the Lord's day that day he was told to write the prophecy, which he would be doing as it was given to him that day. Thanks be to God.
