No I'm saying everything about protestantism since day one was inspired by Satan to fragment Christians and that the notion that one personal alone is somehow uniquely guided by the Holy Spirit to the extent of knowing more than the Church Fathers is deliberatly inspired by Satan so as to create numerous opposing sects and replace Christianity with a bunch of arguing sects all of which feel they have divine authority.
Well, at first it sounded like you were saying that the way to know a false teacher was by his murderous behavior, ie fruits. It now seems like you have reconsidered looking too closely at behavior, good idea on your part, and are simply defaulting to the old we're right and you're wrong. And your proof that you are right, "the Church Fathers". This must explain why RCs so often drop names of such fathers when trying to prove a doctrine that doesn't exist in the bible.
I still maintain that the bible warns about false teachers. When I hear teaching that is not in the bible and that is often the very opposite of what the bible say that is pretty simple proof that a teacher or even a whole denomination is false. The bible places unlimited confidence in itself but not in man. The bible's definition of the Church has never been the RCC so any verses about the Church can only be about believers, not a particular denomination.
All Protestantism and all personal leading by the Holy Spirit are "inspired by Satan?" That's astounding. At least this candor puts the lie of ecumenicism in its rightful place.
Some people prefer to bow to other men, to "church fathers" and to assorted priests and wooden saints rather than to Jesus Christ alone, the only mediator between God and man. These people tend to be authoritarian by nature.
What you call "satanic" I call God-given and God-ordained because the word of God is perfect and will accomplish everything it was sent to do. Part of its mission is to separate the wheat from the tares...
"For there must be also heresies among you, that they which are approved may be made manifest among you." -- 1 Corinthians 11:19
No man can stop the reformation of God's church. As Calvin, a man blessed by the same grace as all believers, wrote...
"...the restoration of the church is the work of God, and no more depends on the hopes and opinions of men, than the resurrection of the dead, or any other miracle of that description. Here, therefore, we are not to wait for facility of action, either from the will of men, or the temper of the times, but must rush forward through the midst of despair. It is the will of our Master that his gospel be preached. Let us obey his command, and follow whithersoever he calls. What the success will be it is not ours to inquire. Our only duty is to wish for what is best, and beseech it of the Lord in prayer; to strive with all zeal, solicitude, and diligence, to bring about the desired result, and, at the same time, to submit with patience to whatever that result may be." -- John Calvin
