The difference between Holy Spirit And Holy Angels

Holy Angels and Holy Spirit are different entity. Holy Spirit is greater than the holy angels. What Christ send after he risen to heaven are Holy angels only not the Holy Spirit. The example of difference of Holy Spirit from Holy Angels is St. Michael talking to Moses as Holy Spirit. When Archangel Michael appear as bush of fire Michael say he is God that because the Love within Michael's heart is the Holy Spirit talking to Moses not Michael. But when St.Michael appear to Moses as himself he never introduce himself as God anymore. And he prevented Moses from worshipping him.
