 The second Archbishop of Mexico (1551–72), the Dominican Alonso de Montúfar, wrote to the king in 1560 protesting the importation of Africans, and questioning the "justness" of enslaving them.Tomás de Mercado was a theologian and economist of the School of Salamanca who had lived in Mexico and whose 1571 Summa de Tratos y Contratos ("Manual of Deals and Contracts") was scathing about the morality of the enslavement of Africans in practice, though he accepted "just-title" slaves in theory.The Church's view on the African Slave Trade in Latin America mimicked that of which they treated it in Europe, as in they did not view them as morally equal.
