Photographs of a plaque thanking [a drug cartel] kingpin for building [a] new modernist church with a 20-metre high metal cross ... caused a scandal when they were published in a national newspaper in October 2010. The scandal has faded but the plaque remains - an uncomfortable reminder of the influence of the drugs culture in the Mexican Catholic church. Narco-church relations are nothing new. In 1993 the leaders of the Tijuana cartel held a secret meeting with the papal nuncio in Mexico City as part of an effort to distance themselves from a chaotic shootout that had killed a cardinal. The meeting was brokered by a Tijuana priest who had received bountiful donations over the years. Pope Benedict [expressed] concern about such relations at the start of his papacy. But while the bishops have since periodically stressed that drug money can never be purified ... they have done little else. While the pope is expected to talk about the violence battering Mexico during his three-day visit ... observers believe he is unlikely to make more than a passing reference to corrosion of the church itself. In the meantime one cartel has sought to take propagandistic advantage of the visit. Banners signed by the Knights Templar cartel hung up around Guanajauto on Sunday welcomed the pope and promised to refrain from acts of war" during his visit. That same cartel was suspected to be responsible for the appearance of 10 severed heads outside a slaughterhouse in another state on the same day.
