Following is Part 2 of "A Dangerous Doctrine", by Batsell Barrett Baxter...
Both Church and State
The Roman Catholic Church is more than a church; it is a state. It is a sovereign power, having legislative, executive, judicial powers, including the power of coercion. The Catholic state has a full civil government with a flag, police force, courts and postage stamps. Currencies, in the form of gold and silver coins, bearing the effigy of the Pope, are issued and some five hundred national citizens use Vatican passports when they wish to travel. The Roman Catholic Church - operating as a State - sends ambassadors to fifty-two different nations and invites ambassadors from other nations, including our own, to be sent to it.
Ostheimer and Delaney, in their book, Christian Principles and National Problems, with the imprimatur of Cardinal Spellman, on page 898 put it this way: “The doctrine of the Church…is that the State must profess and promote not any religion, but the one true form of worship founded by Christ and continued today in the Catholic Church alone. Such a public profession…will bring the State into some relation with Catholicism, the only complete expression of God’s revealed truth. As an ideal, then, Church and State should be united in their efforts.
