You mean that one of your birth angels is Gabriel? Or you are petitioning Gabriel? Or your lunar birth angel is the one ruling the issue in question?
Just omit the third angel from the script:
“Angel Gabriel, help me to bring about this matter by and through your great power.”
“Angel (birth angel and angel ruling issue) please help me bring about this matter under your dominion by and through the Great Lunar Angel Gabriel.”
Yes, my birth angel is ruling the issue at hand. Thanks, I wanted to be sure.
@Alan, you are very welcome. Excellent question.
