He had devoted a considerable amount of time to research and writing.
TAN Books published two of his works criticizing the post-Vatican II liturgical reform. One was a commentary and new translation for
The Ottaviani Intervention, a key document in the traditionalist movement. The other,
The Problems with the Prayers of the Modern Mass, argues that the
1969 Roman Missal systematically omits Catholic doctrines (e.g. the uniqueness of the Church); it has been translated into at least four languages. Cekada's bibliography includes apologetic, analytical and controversial articles on a great variety of topics: the errors of Vatican II and the post-Conciliar popes, canon law, seminary formation, the
Feeney case, the Mass of Paul VI, the pre-Vatican II liturgical changes, the validity of post Vatican II sacramental rites, questions in moral and pastoral theology, and the case for sedevacantism, the
Schiavo case, the Society of St. Pius X, intramural traditionalist disputes, and rubrical matters. In 2010 Cekada completed
Work of Human Hands: A Theological Critique of the Mass of Paul VI, a 468-page study of the post-Vatican II liturgical reform published by Philothea Press which argues the new rite permits “irrelevance” and “destroys Catholic doctrine concerning [...] the Real Presence". Unusually for a publication by a prominent sedevacantist, the book received praise from mainstream Catholic reviewers. ==References==
