   • 2017, Stoyan Tanev, Energy in Orthodox Theology and Physics: From Controversy to Encounter, quoting and translating the conclusions of the Fifth Council of Constantinople (1351), page 2:

     We hold, further, that there are two energies in our Lord Jesus Christ. For He possesses on the one hand, as God and being of like essence with the Father, the divine energy, and, likewise, since He became man and of like essence to us, the energy proper to human nature. […] Energy is the efficient and essential activity of nature; the capacity for energy is the nature from which proceeds energy; the product of energy is that which is effected by energy; and the agent of energy is the person or subsistence which uses the energy.
