False. The tribulation period is two periods of 1260 days each. Clearly laid out in Revelation.
Oh brother, where do you dig this stuff up? "Jacob's time of trouble" is not 1,260 days. We don't know how long the 7 Last Plagues will plague the Earth but I can assure you that 1,260 days of nothing to drink, scorching sun, diseased flesh will kill everything in a matter of weeks, much less 1,260 days. Besides, when the last plague is poured out, "there was silence in heaven for about the space of an hour" - when all the host of heaven accompany Jesus on His return trip to gather us - and if a "day" is equal to a prophetic year (day/year principle), then an "hour" is about 15 days for the duration of the plagues - I can't prove I'm right, but you can't prove me wrong.
Satan does not counterfeit Christ.
Are you sure?
Christ is our High Priest.
The papal leader is their high priest.
Christ has His heavenly sanctuary.
The papacy has the Vatican.
Christ has His ministry of intercession
The papacy has the intercessory priesthood.
Christ has the Sabbath
The papacy has Sunday.
Christ ministers in the Holy Place among the candlestick, censure, and shewbread.
The papal Antichrist uses candles, the censure, and the Bread of the Presence.
Christ bears the holy priestly garments and robes.
The papal authorities wear priestly garments and robes.
Christ is called "Everlasting Father".
The papacy calls their leaders "father".
Of course, I could list a lot more but I list these not for your benefit, but for those who might be led astray by your false ideas.
