In my personnal humble opinion and ,As a human of strong faith , I do not believe any religious leader has a platform before the US government. We have separation of church and state. Pope will get loads of criticism about him addressing the congress, He should’nt address the congress. Pope Francis should just skip speaking at political forum and go on visiting the children’s with disabilities and special needs like Mother Teresa used to do. Although What i think is , Pope Francis, ought to be challenging the Islamic misrepresentation of Christian characters and ideas presented in the Quran and Hadiths. It is actually Islam that is mocking and provoking the Christian Faith and its literal prescriptions for the fate of Christians is more a 2nd Amendment issue than 1st Amendment.
