When the law refers to morality, it necessarily pertains to public and secular morality and not religious morality... Accordingly, in order for a conduct to be considered as disgraceful or immoral, it must be ''detrimental (or dangerous) to those conditions upon which depend the existence and progress of human society'' and not because the conduct is proscribed by the beliefs of one religion or the other. (Leus vs. St. Scholastica's College West Grove, G.R. No. 187226, January 28, 2015)
