What is the Church’s understanding of the heavenly powers?

Origen describes the Church as the assembly of the believers, the Christian congregation, whom God serves through the priests¹⁰²⁵ and who are joined with the heavenly powers: “a place of prayer, the spot where believers assemble together, is likely to have something gracious to help us, since angelic powers are placed near the throngs of believers, as well as the powers of our Lord and Savior Himself, and the spirits of the saints — I think both of those who have already fallen asleep and clearly of those who are still alive, even though it is not easy to say how.”¹⁰²⁶
