 Makes the sign of the cross on the forehead and on the heart. To mark you. To mark you as one redeemed by Christ the crucified. You've been sealed by the Holy Spirit. In worship, we begin and end the service with our great triune God. We begin in the name of the Father, Son, and Holy Spirit. And we end with the blessing of the triune God. The Lord bless you and keep you. Make his face shine on you and be gracious to you. May he look upon you with favor and give you peace. That's Trinitarian.
