Burning candles is a sign of divine life in the Mexican culture for the divine presence of God. Ancient Mexico Christians burned candles for prayer and funeral processions. They were also used for mass and liturgical march. Candles were used to show respect for the Blessed Sacrament and throughout prayer ceremonies.
Candles are burned to symbolize good faith, grace, and wisdom. They are lit during Sacrament of Baptism, Holy Communion, prayers, and funeral processions. They also represent the dedication for divine life. The light from candles in current catholic Mexican tradition also signifies Christ or the presence of the divine spirit. This is why Catholic churches burn candles in honor of Jesus.
