Roman Catholic theology on faith and morals is the website of Ronald L. Conte Jr., a Roman Catholic theologian and Bible translator. Read a summary of my work as a lay theologian and an explanation of my credentials. You can also read my blog, the Reproach of Christ, or follow me on Twitter.

Please note that each of my theological arguments on any topic stands on its own merits. Sometimes I express a theological opinion on a matter of pious disagreement among faithful Catholics. Other times I express, in my own way, the true teachings of Tradition, Scripture, Magisterium. The faithful are free to disagree with my theological opinions, but they are not free to disagree with the teachings of the Magisterium.

The Catechism of Catholic Ethics: A work of Roman Catholic moral theology

The Catechism of Catholic Ethics is a comprehensive explanation of Roman Catholic teaching on the basic principles of ethics, including: the eternal moral law, natural law, the three fonts of morality, the principle of double effect, the principle of cooperation with evil, the use of personal judgment and conscience, moral certitude, temptation, and differing degrees of sin and culpability. This book clarifies for the reader the distinction between positive and negative precepts, between interior and exterior acts, between doctrine and discipline, and between imperfection and sin. This work also covers magisterial teachings on specific types of acts, including: lying, theft, murder, just and unjust violence, slavery, just and unjust war, abortion, contraception, in vitro fertilization, sexual sins and marital sexual ethics. The book closes with a long chapter on Catholic salvation theology, called grace and salvation. Available in Kindle format at, and in paperback at: and
