Christianity, as we know it, began in Roman territory, and started out as the "Roman Catholic Church". Christianity is obviously a European-centered religion, including Protestants and Anglicans. The European ethnic group includes Greeks and Italians, who are generally considered "White" in the U.S.
You are wrong david.
Christianity expanded through the roman provinces first - and it took many decades before it reached continental Europe, much less the Italian Peninsula. Europeans were a minority on these areas.
The religion first in rosed in Judea - Syria. Then expanded through Egypt and Anatolia. The major centers of christian congregations in early roman empire where Jerusalem, Antioch, Alexandria, Damascus and Cyprus.
Ethiopia was also a major center of Christian expansion. The religion expanded around the same time as it did throughout the roman empire, although before it reached the italian peninsula. Ethiopia was never part of the empire.
The large majority of early christians
were not caucasians. They were arab, jews and africans. Christianity is not an "european" creation.
It is also speculated that christianity was originally more popular with slaves and freedman, which the core of them were not italian. The core roman uper-classes were mostly pagan until the roman state adopted christianity.
PD: see what I mean? you need to back your claims with data.
