Evangelii Gaudium §69

69. It is imperative to evangelize cultures in order to inculturate the Gospel. In countries of Catholic tradition, this means encouraging, fostering and reinforcing a richness which already exists. In countries of other religious traditions, or profoundly secularized countries, it will mean sparking new processes for evangelizing culture, even though these will demand long-term planning. We must keep in mind, however, that we are constantly being called to grow. Each culture and social group needs purification and growth. In the case of the popular cultures of Catholic peoples, we can see deficiencies which need to be healed by the Gospel: machismo, alcoholism, domestic violence, low Mass attendance, fatalistic or superstitious notions which lead to sorcery, and the like. Popular piety itself can be the starting point for healing and liberation from these deficiencies.
