History in general and Church history in particular have been massively distorted, especially through the lense of an American. Apologetics in an "online" format is dangerous too, and I am certainly not blessed to engage in it, but what I will say is this: Jesus, the Christ, did establish a Church (His body) on Earth and it does have a particular order and function that is distorted in both the Protestant and Roman Catholic traditions. Christianity has inarguably transformed culture BUT if you presume that culture is downstream from religion , than innovations to the Christian tradition like the filioque and sola scriptura will (and already have) lead to cultural denigration.
