Brazil is reportedly experiencing a dramatic religious transformation, with evangelicals set to outnumber Catholics by 2030.

Once the world's largest Catholic nation, Brazil has seen a steady decline in Catholicism, with evangelical Christianity growing rapidly.

In 1950, 93 per cent of Brazilians identified as Catholics, according to Faithwire,

However, since 1991, the Catholic Church has lost about one per cent of followers each year.

Evangelical Christianity, once a minority, has exploded in popularity, with mega-churches and thriving congregations across the country.

Church leaders like Andre Fernandes and Lourival Pereira credit the movement’s success to small, Bible-based home groups, while J.B. Carvalho who pastor's a church in the capital city of Brasília told the outlet: “We started the church in 2003 with only 25 people.

"Today, we have about 12,000 people in Brasília alone.”

Evangelicals have also gained political influence, with more than 30 per cent of Brazil’s lawmakers identifying as evangelical.

Since 1922, the number of evangelical churches has skyrocketed from a handful to nearly 110,000, with 17 new churches opening daily, as reported by CBN news.

Prayer and worship, led by influential artists like Ana Paula Valadao, have played a key role in the movement.

This shift has drawn former Catholics back to the faith, with many churches embracing contemporary, Pentecostal worship styles.

As a result, the once-dominant Catholic Church in Brazil is seeing its influence decline faster than expected.
