Saint Juan de Ribera…

…judges Francis’ idea that Christians and Muslims share the same faith

  • Islam does not deserve the name of religion

But that which has already been written is sufficient as the conclusion of this article, which is so important for your salvation; which is to say, for the destruction of the perverse sect of Mohammed. Because if we have proven that the finality that it proposes is entirely bestial, and unworthy of the authority of man; and if its author was an adulterous man, a perjurer, a thief, a murderer, a blasphemer, and most ignorant in human and divine letters; and if all the things contained in this his law were fables in philosophy and errors in theology, even for those who do not possess the light of reason, and the customs he teaches are a school of bestial vices; and he did not prove this his new sect with any motive, neither supernatural with miracles nor natural with reasons, but solely spread it by the force of arms, violence, fictions, lies, and carnal license, what remains other than it is a sect that is impious, blasphemous and vicious, an invention of the devil, and the direct way to the fires of hell, and that it does not even merit the name of being called a religion. (Saint John de Ribera. Catechism for the Instruction of the New Converts of the Moors, 1599 AD)
