The invocation of the Trinity ends nearly every collect in the Episcopal Book of Common Prayer. It is a reminder that God, though One, is also Father, Son, and Spirit. During the Last Supper, Jesus prays for his disciples and “for those also who believe in Me through their word; that they may all be one; even as You, Father, are in Me and I in You, that they also may be in Us, so that the world may believe that You sent Me. The glory which You have given Me I have given to them, that they may be one, just as We are one.” (John 17:20-22)
God who is in Jesus, is also in you and me. The Prayer of St. Patrick asks that Christ be in me, above me, below me, behind and before me. In the same way God and the Holy Spirit are equally present to surround and guide us.
Would your daily life be different if you remembered that the Trinity is present within and around you?
