First time player playing as a tempest cleric.
As I understand the rules, a cleric of any domain has access to all the general cleric spells (i.e. not the ones that are only accessible to certain domains). However, my DM informed me that my god (custom storm god that he made up) would not allow me to cast Animate Dead because that's outside his domain. He also said that while I could cast first aid type resurrection spells like Revivify, the more powerful, return-the-soul-from-the-afterlife type spells would be a no-go. However, he'd let a life domain cleric use those spells more freely.
Are there any official sources that these rules are based off? As far as I can tell this is just a homebrew push to make the domain more thematic.
