The Catholic Church gets the bulk of its doctrines from Scripture. Are you Pauling on us again?
Are you trumping the Gospels with misinterpretations of Paul? Are you bringing the blackness of ancient heresies back into modern dy?
Do you not pay attention to the Church Fathers, thinking that you are wise beyond them, that you are true beyond them, that you by yourself (with the crutch of the sainted Calvin) are capable of forming your own theology that is correct and true? Are you comparing one man to all? Are you saying that the Lord saying that He will accept men into Heaven is equivalent to sending them to hell?
Reformed theology is poor and sparse. I do not wonder that it has not the attractiveness to mankind compared to the Gospels. The only question is in what year the Calvinist gospel will finally suicide. The Shakers did some years back. Do we have some bets on the Calvinists?
Why just the "bulk"?
Can you detail which doctrines or dogmas you profess that are not Scriptural?
Obviously, you have never read The Westminter Confession, the Heidelberg Confession, or The Canons of Dort.
Why don't you educate yourself better before presenting yourself as knowledgeable about The Reformed Faith?
