Trinity Sunday – I saw the Lord (Stainer)

…I saw the Lord sitting upon a throne, high and lifted up, and His train filled the temple. Above it stood the seraphims: each one had six wings, and with twain he covered his face, and with twain he covered his feet, and with twain he did fly. And one cried unto another: Holy, holy, holy is the Lord of Hosts: the whole earth is full of His glory. And the posts of the door moved with the voice of him that cried, and the house was filled with smoke. (Isaiah 6:1b-4)

O Trinity! O Unity!
Be present as we worship Thee,
And with the songs that angels sing
Unite the hymns of praise we bring.
