I'll have to dig up my notes for that - in "spiritual studies" - from recollection it is basically, after God, is the son(mighty power) and the God the holy spirit, then follows the angels and saints, (Only those "saints" recognized in heaven(outstanding perfomers and barkadas of JC) and have received their rewards - Mother of God, Holy Queen Mother Mary already proclaimed - Iba na ang malakas), Inheritance Power - (Children of God - now on earth and those who are here now and have special assignments) - Satan and his angels have also power - they are of the same category of the angels/saints - God assigned archangel michael to fight satan...when satan challenge God during the uprising, God said, it would be unfair/unjust for him to fight satan, because satan is just His creation - so Archangel Michael has to do it to be fair.

By the way man is the lowest level of power - but there is also power in numbers, such taht each one has 1 volt. But if man unites for good and combines - fervently prayers - 100 men/women can produce so much power as well...and perhaps exponentially - as in squared. it is like a battery linked together although additive, man's power when "synergistically" combined is beyond what you can alone achieve. The power of "WE". one plus one is not equal to two but much much more - exponentially equal to four. 3 becomes 9...etc.,can you imagine what combined prayers can do...
