There is nothing arrogant about it at all. I have never made a secret of it. Have you never heard that there is much rejoicing in heaven over one sinner repenting? 
I know as much about the Catholic Faith and the Catholic Church as you or anyone else who posts here does. I know what Fr Rohr teaches and what he supports and it is not what the Catholic Church teaches or supports. I am entitled on these grounds to criticise him and his order for allowing him to publish his erroneous opinions.
