The Maronite Catholic Church affirms that Matthew 28:19 establishes the trinitarian formula as the form of baptism. Baptism is administered in the name of the Father, Son, and Holy Spirit, and this formula is essential to the sacrament's validity. The Council of Trent reaffirmed the necessity of the trinitarian invocation for valid baptism. In Maronite tradition, while various Eastern liturgical formulas exist, all genuinely Christian baptisms require the invocation of the Trinity.

The Maronite liturgical tradition, rooted in the Syriac fathers, maintains the trinitarian formula as inviolable. Baptism is understood as incorporation into the Trinitarian mystery and participation in Christ's death and resurrection. The formula is not merely verbal but sacramentally efficacious.
