On 27 October 2020, Pope Francis acknowledged that Cristina was killed in odium fidei ("in hatred of faith"), approving the ceremony of her beatification, which occurred 10 December 2022.

[5] Her baptism was celebrated on 15 August in the local parish church of Nossa Senhora da Piedade in Barbacena; she received her Confirmation on 22 April 1965 in the San José basilica from Archbishop Oscar de Oliveira before making her First Communion at the school that the Vincentian Sisters managed on 26 October 1969.

[3][4] Mrad Campos, affectionately known as 'Cris', studied at the Immaculata College that the Vincentian Sisters managed, becoming known for her kindness and for her above-average intelligence that set her apart from her peers.

On 15 August 1982, she relocated to Juiz de Fora alongside her brother Roberto to a small rented apartment that was located near the church and school where Mrad Campos was to take her medical entrance examination.

Pope Francis authorized a decree on 27 October 2020 that determined that Mrad Campos had died "in odium fidei" (she preserved chastity in the name of faith) and approved for her to be beatified.
