Arius mentioned.
I am not Catholic and could be considered a protestant of Protestantism (LDS). However, I believe that coercion/violence in the act of establishing the doctrines of God is wholly unchristian. I can find nothing in the life(example) of Christ which would suggest that this would be acceptable to him or those who profess his faith.
Furthermore, I believe that the stated example of the father disciplining his son as a metaphor for a church disciplining non-conformance is totally out of place.
If coercion/persecution is OK to Catholics as a church, then the persecution of Christ and Christianity by the Jewish Elite, could be similarly described as a necessity to punish non-conformity, and could serve equally in justification of the various murders committed by the inquisition. Indeed, if the inquisition was sanctioned by God, why is it not practiced today?
Last of all, history has proven the justness of Catholic non-conformists in the past, such as the example of Martin Luther. In the 1500s, Martin Luther was excommunicated as a heretic, although, the modern Catholic church has modified the church position to conform to most of the self-same criticisms that Martin Luther was excommunicated for.s.
