The Rev. Father John G. Arintero, O.P. and S.T.M., was a priest and author of the twentieth century. In the comprehensive The Mystical Evolution in the Development and Vitality of the Church, he exquisitely details the nature of the supernatural life, as well as the various progressions of how to get there. Father Arintero's work was originally printed in 1949 by the B. Herder Book Company, with the Nihil Obstat, Imprimatur, and Imprimi Potest. It was also published by TAN in 1978.
