The liturgical color of Pentecost is red, which symbolizes fire and the blood of Christian martyrs.
On the Sunday following Pentecost we celebrate the Holy Trinity. We marvel at our Creator, Redeemer, and Sanctifier who has revealed himself to us as three separate Persons, but also as one undivided and indivisible God. We cannot fully understand the mystery of the Trinity, but we receive the mystery by faith.
The liturgical color of Holy Trinity is white, which symbolizes the holiness, purity, and perfection of God.
The remaining Sundays after Holy Trinity are numbered as Sundays “after Trinity” or “after Pentecost.” Throughout this post-Pentecost season we no longer consider the life of Christ chronologically, but each week we focus on a different teaching of the Bible and consider how the life and the teaching of Jesus Christ apply in our lives.
The liturgical color of the post-Pentecost season is green, which symbolizes life and growth in the gospel of Jesus Christ.
