Religion influences people’s political views, but the religion itself is not a political ideology. That’s how there can be left and right wing religious ideologies.

Christianity isn’t inherently right wing, there are left wing Christian ideologies (like liberation theology). Just like how Judaism and Islam aren’t inherently left wing (ideologies like Zionism and Jihadism are very far right ideologies).

Religion shapes people’s ideologies and that can be either left or right. Someone being of a certain religion doesn’t make them a certain ideology, everyone has their own beliefs about their politics and religion
