It is absolutely bizarre to presume evil wasn't since the beginning and satan 'used' his words to oppose what God said. And then sin entered in because they believed 'another' - and then The Word came in the flesh.
Then JESUS started HIS Church based on HIS WORD because Jesus is The Word and gave His Church His Spirit as Teacher, lest they be deceived by 'man'. So then the counterfeit wanting to keep his hold on people, he used 'man made words' to 'organize' his counterfeit churches and he has many and they all claim 'they' are the one that is true. So there are many flavors to please man.
GOD'S WORD is the FINAL Authority and JESUS is The Way, The Truth, The LIFE and no one goes to The Father except through Jesus The Word. 'Man made teaching' believers, man brings them to their father of darkness and death.
That is an apt description of those who reject the Church founded by Jesus. Do you mind if I use it?
Peace be with you
