Benedict decentralized beatifications, and in 2007 reverted the decision of his predecessor regarding the conduct of papal elections by the changing the §75 of "Universi Dominici gregis". In 2007 he set a Church record by approving the beatification of 498 Spanish Martyrs. His first encyclical "Deus caritas est" discussed the nature of love and how it informs one's participation in a just society. In an address at the University of Regensburg, Germany, Benedict maintained that in the Western world, to a large degree, only positivistic reason and philosophy are valid. Yet the world's profoundly religious cultures see this exclusion of the divine, as an attack on their most profound convictions. A concept of " reason" which excludes the divine, is incapable of entering into the dialogue of cultures, according to Benedict. During this Regensburg address Benedict quoted a Byzantine emperor who said Muhammad had brought the world only things "evil and inhuman". After the Pope explained his quote, the dialogue continued, with cordial meetings of Islam representatives in Turkey, and the ambassadors of Muslim countries in 2007. A May 2008 declaration agreed on between Benedict and Muslims, led by Mahdi Mostafavi, stressed that religion is essentially non-violent and that violence can be justified neither by reason nor by faith. Pope Benedict has spoken out against human rights abuses in China, Darfur, and Iraq and encouraged protection of the environment and the poor. He spoke strongly against drug dealers in Latin America and Catholic politicians supporting abortion laws.
