The reason they call it faith is because it is unprovable and not based on demonstrable fact. If you prefer, you can choose someone else's faith or you can make up your own. The someone else sort gathers credibility with aging. With aging, it achieves a dogma. Dogma become fighting words and fighting words become killing words. People die for their faith and kill for their faith, and all that based on the unprovable and thus the unknowable.
Faith in politics is worse than politics in faith. Hearing a politician say, "You will be in my thoughts and prayers" is a tooth cracking experience. It would be refreshing to hear, "You will not be in my thoughts and prayers." That would be too honest for politics.
Please Lord, spare us.
