What is the essence of a lie? This question has been debated for centuries and with good reason. The secularization of society pushes the debate forward as Christians face new moral dilemmas regarding communication and truth. While some reject Thomas Aquinas’s teaching on lying as too rigid, Sr. Catherine Joseph Droste, OP will argue that he, in fact, offers sound, coherent, universal principles accessible to all.
