For those who prefer a scriptural bent to their interpretation of politics:
In interpretation of the Gospels, Pope Francis represents the ascendency of the Epistle of James (the brother of Jesus and Chief Priest of the Temple) over the epistles of Paul (the tax collecting, egomaniacal suppressor of the Jesus Church). When James and the other Apostles agreed to admit non-Jews into the Church they had no idea it would open the door to the rest of Paul’s theology. In response, James wrote his Epistle in order to refute Paul.
Basically James and Jesus maintained you are not getting into Heaven by faith alone but by good works, whether or not you have “The Faith.”
If you want to put it into religious terms, politics in the US today to a great extent reflects the conflict between those who believe in faith alone whether in God or Country without concern about the fate of others and those who believe their God or Country demands a commitment to the welfare of all.
