Strategy: Sovereignty and Faith

As opposed to other religious civs, the early game scramble is a little less hectic. Though you should still hurry for the best beliefs, you have to worry less about lacking a religion, since you can always found on. Particularly useful, if you take Piety, is the "Evangelism" belief. Since you'll likely found a religion late, corroding existing religion's pressures helps you squeeze into the populace. Additionally, when paired with Interfaith Dialogue, your late start can even be beneficial, since there's more cities that will yield science. Back onto the subject of buildings however, the lack of need to get the early pantheon means that you can put off the shrine until later until the build order, opening room for other buildings, like circuses. Grabbing land is important, as the faith you need to produce will be largely dependent on the cities you'll own.Mid-game, the majority of warmongers will be making hostile advances, particularly on potential faith and culture players. Your Swiss Guard will uphold your papal power in the face of the heavens, netting you additional culture. Once a critical mass of cities is reached, building up to basilicas is a priority for the extra faith and pressure from the Grand Temple. Early on, using prophets to make holy sites would be a good idea in order to stock up on faith. After a decent faith production is built, swapping to missionaries after Evangelism is a powerful strategy. Alternatively, buying city states with faith is also a decent strategy, since they'll add to your collective producers, but the mid-game happiness slump can put a stop in the number of cities that can be held. That being said, the dual bonuses of Notre Dame can mend that.Late-game, stacking museums will be the ticket to cultural victories. With the extra artist slot in the basilica, your generation of great artists will be slightly ahead of the competition. With the Aesthetics finisher, the museums will give double tourism, and with your religion's ability to corrode others, you'll soon begin getting the tourism benefits that major religions enjoy. Though it might be tough, getting World Religion passed will help greatly, making your religion even harder to fight off.
