Here’s an opening call to worship litany for Transfiguration Sunday written by Thomas Weitzel.
The Lord, the God of gods has spoken;
he has called the earth from the rising of the sun to its setting.
Out of Zion, perfect in its beauty,
God reveals himself in glory.
The Lord is king; he is enthroned upon the cherubim.
The Lord is great in Zion;
he is high above all peoples.
Let me announce the decree of the Lord:
"I myself have set my king upon my holy hill of Zion.
"You are my son; this day have I begotten you."
Let them confess his name,
which is great and awesome.
Proclaim the greatness of the Lord our God
and fall down before his footstool.
