Gratia gratum faciens, 'sanctifying grace.' The expression is taken from St Paul, Eph. i, 6, gratiae suae in qua gratificavit nos, echaritôsen hêmas. Hence the celebrated kecharitômenê of Luke i, 28, might be translated gratificata, or grata facta, or per grata facta, to express the fulness of the Greek perfect.
