Who was responsible for the legalization of Christianity?

Answer 1

When the word "Christianity" is mentioned, please note that it is of a Spirital Dimension. Therefore , as the word "'Legalization" is of an Earthly dimension, there is no real connection . So a term like "the Legalization of Christianity" cannot exist.

If you speak of Christianity... there is but One Judge. And He does not measure things according to Earthly niceties!

The legalization of anything depends on the will of the people, or the rule of a dictator, or common international self-preservation.

Emperor Constantine provided state patronage to the Catholic-Orthodox sect of Christianity, thus removing any doubt that Christianity had become legal. Although Christians still made up a very small proportion of the population, Christian bishops were made equal to the pagan religious leaders and hence took on some of the accoutrements that had previously been reserved for pagan leaders.
