I understand your confusion many Druids do not honor the Teiple Goddess however some do myself being one of them. This is my version of the Gorsedd Prayer by Iolo Morganwg. Here is the moral traditional version:
"God, impart Thy strength;
And in strength, power to suffer;
And to suffer for the truth;
And in the truth, all light;
And in light, all gwynvyd;
And in gwynvyd, love;
And in love, God;
And in God, all goodness.
And thus it ends."
From the Great Book of Margam.
And here is a longer version in complete English:
"Grant, O God, Thy protection;
And in protection, strength;
And in strength, understanding;
And in understanding, knowledge;
And in knowledge, the knowledge of justice;
And in the knowledge of justice, the love of it;
And in that love, the love of all existences;
And in the love of all existences, the love of God.
God and all goodness."
So yes traditionally the goddess isn't who is honoured in this prayer however I favour the Triple Goddeas and therefore posted it without thinking I do apologise for the confusion.
