The Directory on Popular Piety and the Liturgy (DPPL) upholds that Christian worship originates and is brought to completion in the Spirit of Christ, which dispenses truthful liturgical devotion and realistic manifestations of popular piety. A vigorous engagement of evangelization and culture is embodied in the Sabuaga Festival, an Easter Sunday celebration in Sto. Tomas, Pampanga. It is a collaboration of the Catholic Church (St. Thomas the Apostle Parish) and the Local Government Unit (Sto. Tomas). This paper argues how a true and fruitful harmony between liturgy and popular piety is achieved in the Sabuaga Festival. Hence, the researcher articulates the following, namely: First, the dimensions of the Sabuaga Festival that make it an expression of popular piety. Second, the principles offered by DPPL for the true and fruitful harmonization of liturgy and popular piety. Third, the pastoral action plan, entitled: “An Authentic Pastoral Action of the Liturgy: Towards Building upon the Riches of the Sabuaga as a Popular Piety,” which provides suitable catechesis for the harmonization of Liturgy and Popular Piety in the Sabuaga Festival.
