[Greek] ἐνέργημα (energēma), [Latin] operatio: effect, operation, energy, activity; 1Cor.12:6,10
Background information:
Greek Hellenism: This term means what is effected, act, action, operation, and labors. Cosmic or physical forces are at work in man or in the physical world. Polybius’ Histories 4.8.7 states “Not only is it the case that the same man has an aptitude for one class of activities and not for another, the same will be exceedingly acute and exceedingly dull.” Aristotle’s Nicomachean Ethics 1101 states “May not we then confidently pronounce that many happy who realizes complete goodness in action, and is adequately furnished with external goods?” Polybius’ Histories 1.13 states “In Greece at the same time the war called after Cleomenes was in full action.”
Old Testament: This term, primarily occurring in Wisdom, 2Macc, and 3Macc, pertains to the work of divine or demonic powers. That I might know the organization of the universe and the force of its elements (Wis.7:17). This was the act of God who rules over all things (3Macc.5:28). Or if they were struck by their might and energy (Wis.13:4).While he lay speechless and deprived of all hope of aid, due to an act of God’s power (2Macc.3:29). But this was an act of the invincible providence of Him (3Macc.4:21).
New Testament: This term means deed, working, and activity. These charisms come from the Spirit, which distributes to others as He sees fit. The Corinthians seemed to have developed an esteem (interest) in tongues. These charisms are gifts, graces (outside of human terms), forms of service, and expressions (in purpose and effect.) All of these are workings or activities.
Scripture:
“There are different workings but the same God who produces all of them in everyone. 1Cor.12:6
God (and the Holy Spirit) distribute these gifts to certain person according to His providence.
Conclusion:
Energy, energetic, operation, operational
In the Greek Hellenistic era, this term refers to divine, supernatural, and ordinary actions. Such ordinary actions (workings) can include sexual intercourse, operating in surgery, and accomplishing tasks.
In the New Testament, the Holy Spirit is source of all charisms and gifts. Each person is given gifts according to his capabilities or capacities.
There is not much else that needs to be said. I really do not expend any more energy in illustrating this term. So take it easy from your own workings.
