Celso Tavares grew up Catholic, and even considered the priesthood, but became fascinated and compelled by what he was discovering in Reformed theology. Later, he would become a Vineyard pastor, and even a leader in the Vineyard movement in Brazil.

Celso never stopped reading and praying and trying to go deeper in his Christian Faith, and it was that persistence that would eventually lead him to reconsider Catholicism, and realize that the fulness of truth he had been seeking all along was in the Catholic Church.
