it all began

Explanation:

Christianity has been practiced in Europe since the first century, and a number of the Pauline Epistles were addressed to Christians living in Greece, as well as other parts of the Roman Empire.As of 2010 Catholics were the largest Christian group in Europe, accounting for more than 48% of European Christians.[3] The second-largest Christian group in Europe were the Orthodox, who made up 32% of European Christians.[3] About 19% of European Christians were part of the Protestant tradition.[3] Russia is the largest Christian country in Europe by population, followed by Germany and Italy.[3]

Since at least the legalization of Christianity by the Roman Emperor Constantine in the 4th century, Europe has been an important centre of Christian culture, even though the religion was inherited from the Middle East and important Christian communities have thrived outside Europe such as Oriental Orthodoxy and the Church of the East since the time of Christ. Christian culture has been an important force in Western civilization, influencing the course of philosophy, art, and science.[4][5]

Europe has a rich Christian culture, especially as numerous saints, martyrs and popes were European themselves. All of the Roman Catholic popes from 741 to 2013 were from Europe.[6] Europe brought together many of the Christian holy sites and heritage and religious centers.[7]
