This lecture was given on January 17th, 2026, at Dominican House of Studies. For more...

Fr. Gabriel O’Donnell argues that the Christian life under grace is a journey of being reordered from within—through a formed conscience, rightly governed desires, and a humble acceptance of God’s love—so that the soul can move from vulnerability and disorder toward purity of heart, virtue, and union with Christ.

Dr. Carl Vennerstrom argues that Christ’s temptation in the desert is a perfect temptation: it reveals every major kind of temptation, shows the devil’s weakness, and becomes a means of salvation rather than merely an obstacle.

Prof. Steven Jensen presents several arguments in favor of the conclusion that the life of a fetus has intrinsic human dignity on account of what a human being is and not merely as an effect of psychological or cognitive capacity, ultimately concluding that the intentional killing of a fetus as a means to save a mother's life is morally impermissible. This lecture was given on February 19th, 2026,...
