Following the Second Vatican Council, the influence of neo-Thomism within the Roman Catholic Church declined, allowing theologians to move beyond rigid, logic-focused interpretations of St. Thomas Aquinas. Instead, they returned to the foundational principles of his theology to address contemporary issues that had been largely overlooked by earlier neo-Thomist thinkers.1

Post-Vatican II theologians applied Thomistic insights to several critical areas:

  • Medical Ethics: Scholars utilized Aquinas’s framework to navigate complex questions in bioethics, grounding their analysis in his understanding of human nature and moral principles.1
  • Spirituality: By emphasizing the role of the Holy Spirit and the anticipation of the eschaton, thinkers integrated Thomistic themes into Christian spirituality, the liturgy, and the sacraments.1
  • Human Rights: Building on the tradition of natural law, theologians applied Aquinas’s thought to the defense of human rights and personal dignity. This approach aligned with the broader post-conciliar shift, where the Church increasingly emphasized the state's moral obligation to guarantee the rights of all citizens.12

These applications reflected a broader effort to engage with the modern world, moving away from the insular, defensive posture of earlier 20th-century neo-Scholasticism.13
