Liturgy Lesson for Trinity Sunday: Our Triune God

May 17, 2008

Trinity Sunday celebrates the great Christian belief in our triune God-one belief (among many) that distinguishes us from any religion, anytime, anywhere. We aren’t pagan polytheists, worshipping multiple gods, but believe in the one true God, expressed in three persons, the Father, the Son and the Holy Ghost-but still, one God. He revealed this truth to us via His Word-Holy Scripture-and much of the New Testament would be unintelligible without it. The Word trumpets God’s Trinity nature: He is one God in Isa 44:6-8; II Sam 7:22 & Deut 6; the Father is God in St. Matt 6:9; St. John 20; Rom 9:25 & II Cor 6:18; the Son is God in St. John 1 & 20; Heb 1: 1-8 & I Tim 3:16; the Holy Ghost is God Acts 5:3; I Cor 2:11 & Ps. 139:7. In liturgical worship, we reverence the invocation of the Blessed Trinity in worship with the Sign of the Cross, made over our forehead, breastbone and to either shoulder-which also commemorates the Jewish Passover-the Blood of the Pascal Lamb, Jesus, applied to door and lintel, forming a cross by which we enter our dwelling place. The Church Fathers correctly represented Trinity with green, as this is the time of growth and fullness, because we have received God’s fullness God, Father, Son and Holy Ghost-and grow in Him!
