I was raised Catholic and never heard of the Vicar Of Christ in my teaching either.
However, if you study the Reformation you will find that respect for the Individual/Personal Property rights/and Personal Responsibility comes from centuries of people reading the Word of God for themselves. That is where YOUR freedom comes from.
Notice that Protestant countries are the most free, as well as the most peaceful, America that was formed on those values.
Notice also that Predominately Catholic countries are poor/enslaved, while the 'church' is full of wealth. (Is that the message of Christ?)
I won't 'suggest' you explore this as it would be an aggressive act, but I will offer the idea.
You are watching your once great country being destroyed from withing. When it stood for the truth, it prospered.
The truth trumps all.
