The article reflects on two important theological categories – sensus fidei and synodality – in the context of their relevance to the life and mission of the Church. The author analyzes these concepts in the light of the documents of the International Theological Commission and the teaching of Popes John Paul II, Benedict XVI and Francis. The sensus fidei of the faithful is portrayed as a supernatural sense of faith, enabling the discernment of the truth of the Gospel and expressing the prophetic participation of the People of God in the mission of the Church. Synodality, in turn, is presented as the Church’s mode of existence and action, which is realized in the communion, participation and co-responsibility of all its members. The article points out the constitutive connection between synodality and the collegiality of the bishops, which is a special form of realizing synodality. The author emphasizes the need for in-depth theological reflection and pastoral indications for a more effective incarnation of these realities in the life of the contemporary Church.
