One cannot commit blasphemy against a denomination. No denomination is God. “ <<<<<
The Catholic Church is not a denomination. Protestants have “denominations” in order to count the ways they oppose the Catholic Church and each other, and out of that variety of ways they have to spring up their own cult to declare their differences from other protestants. Thus the name Protestant. Protest. Protest to the Catholic Church. Denominations refers to Protestant differences.
Catholicism is but one of many man-made religions. Christianity is what we should aim for, not any religion or denomination.
The infighting between Christians is stupid.
