Pleroma (Koine Greek: πλήρωμα, literally "fullness") generally refers to the totality of divine powers. It is used in Christian theological contexts, as well as in Gnosticism. The term also appears in the Epistle to the Colossians, which is traditionally attributed to Paul the Apostle. The word is used 17 times in the New Testament. In Valentinianism it represents as virtualities of the Son.
Etymology
The word literally means "fullness", from the verb plēróō (πληρόω, "to fill"), from plḗrēs (πλήρης, "full").
Christianity
The word itself is a relative term, capable of many shades of meaning, according to the subject with which it is joined and the antithesis to which it is contrasted. It denotes the result of the action of the verb pleroun; but pleroun is either
to fill up an empty thing (e.g. Matthew 13:48), or
to complete an incomplete thing (e.g. Matthew 5:17);
and the verbal substantive in -ma may express either
the objective accusative after the verb, 'the thing filled or completed,' or
the cognate accusative, 'the state of fullness or completion, the fulfilment, the full amount,' resulting from the action of the verb (Romans 11:12, 13:10, 15:29, 1 Corinthians 10:26).
It may emphasise totality in contrast to its constituent parts; or fullness in contrast to emptiness (kenoma); or completeness in contrast to incompleteness or deficiency (hysterema Colossians 1:24, 2 Corinthians 11:9; hettema Romans 11:12).
A further ambiguity arises when it is joined with a genitive, which may be either subjective or objective, the fullness which one thing gives to another, or that which it receives from another.
In its semi-technical application it is applied primarily to the perfection of God, the fullness of His Being, 'the aggregate of the Divine attributes, virtues, energies': this is used quite absolutely in Colossians 1:19 (oti en auto eudokesen pan to pleroma katoikesai), but further defined
