What does one’s faith have to do with abortion legislation?

Assume one’s faith subscribes to no alcohol, no pre-marital intercourse, no meat on Fridays. Does it make sense such tenets should be codified as state or federal laws? That is, should a particular religious faith be the North Star for legislation?

Or, should legislation, consistent with separation of church and state, be faith neutral?

Why can’t one reject abortion in their own lives as part of their Catholic faith, yet recognize that women remain best positioned to make reproductive decisions about their bodies per their faith or non faith?
