The Holy Trinity was seen, Yahweh Elohim.
In the year that king Uzziah died I saw also Yahweh sitting upon a throne, high and lifted up, and his train filled the temple.
2 Above it stood the seraphims: each one had six wings; with twain he covered his face, and with twain he covered his feet, and with twain he did fly.
3 And one cried unto another, and said, Holy, holy, holy, is Yahweh of hosts: the whole earth is full of his glory.
4 And the posts of the door moved at the voice of him that cried, and the house was filled with smoke.
5 Then said I, Woe is me! for I am undone; because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips: for mine eyes have seen the King, Yahweh of hosts.
6 Then flew one of the seraphims unto me, having a live coal in his hand, which he had taken with the tongs from off the altar:
7 And he laid it upon my mouth, and said, Lo, this hath touched thy lips; and thine iniquity is taken away, and thy sin purged. RECEIVED COMMUNION.
