Sorry - I should have been more clear. An example:
At least in Ontario, there has been a fair bit of debate in the past few years about the rights of LGBTQ students at (government-run, taxpayer-funded) Catholic schools.
The schools are required to follow the Charter and the Ontario Human Rights Code except on matters of the Catholic faith. This has meant that there have been secular court cases over the actions of schools and boards that have hinged on fairly detailed questions of Catholic doctrine... e.g. whether Catholic teaching actually forbids a student taking a same-sex date to the prom, or whether there's anything in the catechism that forbids GSAs. Depending on the religious answers, people's rights under secular law are affected.
And then there's our hate speech laws: speech that's likely to incite violence against an identifiable group is generally illegal, but it's excused "if, in good faith, the person expressed or attempted to establish by an argument an opinion on a religious subject or an opinion based on a belief in a religious text."
Weirdly enough, while that exemption seems to apply to all religions across the board, it only seems to be Christians who ever use it.
So those are some of the examples I was talking about. In some cases, the question of what Christianity says about some particular topic ends up affecting secular rights and actual legal consequences.
