Secularity, also the secular or secularness (from Latin saeculum, ‘worldly’ or ‘of a generation’), is the state of being unrelated or neutral in regards to religion.
So, while you might be technically correct as it comes to what the literal translation is: that’s not how it’s used in political discourse.
This is exactly how it is and was used when talking about middle ages. There were secular and religious power, secular and religious courts, and in religious courts church only held authority in spiritual and religous matters. Exceptions to these rules are prince-bishops in HRE and other such examples (papal states) where bishops or pope were civil rulers of secular prinicpalities/states.
