” Yet you decline to either show that or articulate it “
Nope. When we show you EXACTLY what the Universal Church teaches and has taught for an unbroken 2,000 years since Our Lord appointed His Apostles the task of “Teaching all the Nations”, you stick your head in the sand and refuse to look. Willful ignorance is NOT going to be an acceptable excuse on Judgment Day.
When did they start with the assumption of Mary again? How about indulgences, when did that start?
"And He said unto them, Go ye into all the world, and preach the gospel to every creature. He that believeth and is baptized shall be saved...Mark 16:15,16.
"And these signs SHALL follow THEM THAT BELIEVE; In my name SHALL they cast out devils; they SHALL speak with new tongues; (verse 17) they SHALL take up serpents; and if they drink any deadly thing, it SHALL NOT hurt them; they SHALL lay hands on the sick, and they SHALL recover." (verse 18).
If your "Universal Church" has been following the task of "Teaching all the Nations" as appointed by Jesus Christ for an unbroken 2,000 years, then why are there still sick people? and "demon possessed" and why isn't every man hearing those teachers speak in their own language, and why aren't you ridding the earth of serpents and drinking poison so no one has to die needlessly? Notice this says that all these signs SHALL FOLLOW THEM THAT BELIEVE. Not just the apostles. Not just on the day of Pentecost. Not just for priests, or those in "authority". It says clearly that ALL WHO BELIEVE SHALL HAVE THESE SIGNS.
As a matter of fact,every time a believer is baptized they SHALL be able to take their signs to unbelievers and baptize them so THEY SHALL have the signs.
If there hasn't been a worldwide work of Believe and be baptized for remission of sins and these signs SHALL follow, then your religion is a lie. Jesus said these things would follow. And you claim to be the Church He gave this task to. You can't have it both ways. You can't claim to be the One Church that Christ sent to all nations, and at the same time, NOT impart to those new believers the same signs that Christ said ALL BELIEVERS WOULD POSSESS.
