Certainly a traditional Catholic is not going to think his faith is of equal worth to Protestantism, or that a Protestant is just as likely to receive salvation as he is. If he believed they provided equal means to salvation he probably wouldn't be a Catholic. But if we're discussing racial equality, and we usually are when equality is mentioned on Voat, a black Catholic is equally eligible to salvation as any Catholic. And in a Catholic's eyes, likely more than a white Protestant.

But no, religion does not really teach equality in its essence. Certainly not the Semitic religions. Muslims certainly do not believe non-Muslims are equal to non-Muslims, for example, in any really important sense - certainly in matters of the spirit, but even in matters temporal.
