That’s about the extent of it.
Newsom has banned all Christians from singing in church.
Literally the entire Byzantine Catholic /Orthodox Divine Liturgy is sung or chanted. Being liturgical - sacramental Churches, such services are considered essential. Actually, thinking clearly about it, more essential than earthly life, more essential than the physical Universe. Newsom effectively outlawed all Eastern Christian “services” in California, and the actual worshipers have banned (themselves) from thinking too hard about it.
