The feast of St. Valentine was first established in 496 by a Pope you all should know, and whom this Islamist “cleric” should hate. His name is Pope Gelasius I, and he wrote something that all Muslims would simply refuse to acknowledge as valid:

In 494, Gelasius wrote a very influential letter, known from its incipit as Duo sunt, to Anastasius[3]. This letter established the dualistic principle that would underlie all Western European political thought for almost a millennium. In the letter Gelasius expressed a distinction between “two powers”, which he called the “holy authority of bishops” (auctoritas sacrata pontificum) and the “royal power” (regalis potestas). These two powers, auctoritas lending justification to potestas, and potestas providing the executive strength for auctoritas were, he said, to be considered independent in their own spheres of operation, yet expected to work together in harmony.

We owe the very concept of the separate spheres of church and state to Pope Gelasius I.

An extra reason for this Islamist cleric to hate St. Valentine’s Day.
