Well i would disagree on this level of thought found in John chapter 17 - Thy word is Truth
and the clear warnings from the Lord and the Apostles that false christs, false prophets and false teachers would be flooding the world
leading up to His Return.
While Jesus was sitting on the Mount of Olives, the disciples came to Him privately. “Tell us,” they said, “when will these things happen, and what will be the sign of Your coming and of the end of the age?”
4Jesus answered, “See to it that no one deceives you. Matt 24
Dear friends, do not believe everyone who claims to speak by the Spirit. You must test them to see if the spirit they have comes from God. For there are many false prophets in the world. - Apostle John
Apostle Paul : For there will be a time when they will not endure sound teaching, but according to the own desires, having an itching ear, they will gather around
them teachers to
suit themselves,
Apostle Peter: But there were also false prophets among the people, even as there will be false teachers among you, who will secretly bring in destructive heresies, even denying the Lord who bought them,
and bring on themselves swift destruction.
2And many will follow their destructive ways, because of whom the way of truth will be blasphemed.
3By covetousness they will exploit you with deceptive words; for a long time their judgment has not been idle, and their destruction does not slumber.
What is "sound doctrine" and who determines this??? - Only God's Word - "It is written."
Satan deceives the same way today as he did in the Garden - "did God really say...."
So the serpent spewed water out of his mouth like a flood after the woman, that he might cause her to be carried away by the flood.
Revelation 12:15
When i see the Vatican, the Mormon Temple, and others, i check in God's word to see if these are the "wolves in sheeps clothing."
If they speak and do things that God has not approved of in His Word, then we reject those things.
Furthermore the LORD Himself said we are His Witnesses, as such we bear witness to the TRUTH found only in His Word.
My posts always direct the reader to the Word of God and CHRIST.
