How can you call yourself secular while being a Christian state?

the moment you start with a factual premise that there is not a single western state that has abandoned its Christian identity the next question would be how can you be a Christian State and still call yourself secular if you happen to be secular you shouldn't be having let's say a religious identity of your own the problem is we have misunderstood secular secular has always been preceded or it there's a prefix which is constantly missing it is Christian secular not purely secular Christian secularism translates to the following position one the state have shall have a very

specific Christian identity which means it'll also have a very specific denominational identity Catholic or Protestant within Protestant you have the Lutheran church or you have the calvinist church and then subsequent denominations have come about so you need to choose your identity and the separation of the church from the state simply translates to not non- interference of religion with the state but non interference of the state with the activities of the church
