The themes raised in the sermons of the Portuguese Jesuit Antonio Vieira were far ahead of their time. Already in the XVII century, the missionary questions the equality of Europeans, Africans and Indians before God, as well as the injustice of one race oppressing another. In his sermons, he asks his listeners to repent and reject slavery. He wants every colonist to become an apostle in his new homeland: to sow the faith of Christ and take care of the religious and moral education of his slaves. Uncovering the conflicts between the three ethnic groups, Vieira seeks to smooth out these contradictions, pointing out the ways of peaceful coexistence of the three cultures within the bosom of the same faith.
