"In Civilization IV, a temple is defined as a building where the faithful come to worship. Christians call their temples "churches," while Muslims call theirs "mosques," and Jews call theirs, simply, "temples." Temples are far more common than cathedrals, but much less large and ornate. Even the smallest village can possess a temple.
Facing Roman persecution, the earliest Christians worshiped in secret in private homes, catacombs, and the like. The Emperor Constantine I legalized Christianity in 325 AD. Though not a Christian himself as is often mistakenly claimed, Constantine I built many Christian churches across Roman territory, including the Church of the Nativity in Bethlehem, which many Christians believe is on the site where Jesus was born."
"Temples increase a city's happiness and culture. They are especially useful for expanding your civilization's borders during the early game."
