His Holy Spirit is the Teacher of His inspired Word. Catholics are taught by ‘man’ with their ‘man made’ teachings/traditions - seems you are the last to know. There are other flavors of ‘man made’ teachings besides Catholicism; such as, Mormonism, Buddhisms, Islamism.
There is only One Truth - Jesus, The Word and only One Way - Jesus and One Who is Eternal Life - Jesus. All eyes on Jesus - the narrow gate.
The wide gate has an assortment of ‘man made’ beliefs which leads to destruction.
That is exactly the function of the Paraclete Jesus gave to His Church. As for man, you cannot seriously claim that all of your beliefs (theology) you obtained without the help, guidance or teaching of any other humans. Rumor has it that you too are a man.
Let's jut agree to disagree. My recommendation is that you drink more decaf and pray to calm your spirit and work out your own Salvation. I'm doing just fine without you. Besides, your anger and agitation are not healthy for you either physically or spiritually.
Peace be to you
