Colombia does not have an official religion. However, Roman Catholicism is the dominant faith and deeply culturally pervasive. While the national department of statistics does not record the religious affiliations of the population, various studies and surveys suggest approximately ninety percent of Colombians are Christian. The most recent estimates proposed that 79% of the population identify as Catholic whilst 13% identify with Protestantism. A further 6% of the Colombian population is believed to be unaffiliated with any religion whilst 2% follow some other religion, including other variations of Christianity.
Christianity is the largest religion in Peru, with Roman Catholics having the most adherents. Religion in Peru is traditionally related to religious syncretism originating from Catholicism with the ancient Inca religion after the Spanish Conquest. However, Protestant churches of various denominations have developed considerably in the popular sectors over the past 30 years. There has been a slow but consistent advance of irreligion especially among young people in urban areas. Religions such as Judaism and Buddhism, and more recently Hinduism and Islam, are present due to immigration.
According to article 2 of the Peruvian Constitution: “Everyone has the right to freedom of conscience and religion, individually or in association. There is no persecution for reasons of ideas or beliefs. There is no crime of opinion. The public exercise of all confessions are free, as long as they do not offend morals or disturb public order.”
