At the end of the Renaissance, the Valladolid debate (1550–1551), concerning the treatment of the natives of the "New World" pitted the Dominican friar and Bishop of Chiapas, Bartolomé de Las Casas, to another Dominican and Humanist philosopher, Juan Ginés de Sepúlveda. The latter argued that the Indians practiced human sacrifice of innocents, cannibalism, and other such "crimes against nature"; they were unacceptable and should be suppressed by any means possible including war, thus reducing them to slavery or serfdom was in accordance with Catholic theology and natural law. To the contrary, Bartolomé de Las Casas argued that the Amerindians were free men in the natural order and deserved the same treatment as others, according to Catholic theology. It was one of the many controversies concerning racism, slavery, religion, and European morality that would arise in the following centuries and which resulted in the legislation protecting the natives. The marriage between Luisa de Abrego, a free black domestic servant from Seville and Miguel Rodríguez, a white segovian conquistador in 1565 in St. Augustine (Spanish Florida), is the first known and recorded Christian marriage anywhere in the continental United States.
