Father Franca was very close to Cardinal Dom Sebastião Leme, Archbishop of Rio de Janeiro and one of the main Catholic leaders of the first half of the 20th century in Brazil.

[3] He was a member of the National Education Council in 1931 and vice-rector of the Colégio Santo Inácio (Rio de Janeiro).

Franca played a prominent role in the founding of the Pontifical Catholic University of Rio de Janeiro and was also its first rector.

[4] In addition to his solid intellectual, philosophical and theological training, he gained fame for his refutations of Brazilian Protestant pastors and leaders, as well as for the controversies he maintained with them, having written several books to explain and substantiate his positions, such as "The Church, the Reformation and Civilization", "Catholicism and Protestantism" and "Protestantism in Brazil", which can be found in second-hand bookstores and specialized bookstores.

Always suffering from fragile health, he died on September 3, 1948, leaving behind a bibliography with a strong Catholic apologetic connotation and several articles in newspapers of the time.
