According to St Paul (cf. Romans 15:16), you ‘minister’ the Gospel only when, having yourself participated in the light of Christ, you can pass it on actively to others. Then you sow the Logos like a divine seed in the fields of your listener’s souls. ‘Let your speech be always filled with grace’, says St Paul (Colossians 4:6), ‘seasoned’ with divine goodness. Then it will impart grace to those who listen to you with faith.
Elsewhere St Paul, calling the teachers tillers and their pupils the fields they till (cf. 2 Timothy 2:6), wisely presents the former as ploughers and sowers of the divine Logos and the latter as the fertile soil, yielding a rich crop of virtues. True ministry is not simply a celebration of sacred rites; it also involves participation in divine blessings and the communication of these blessings to others.
~St Gregory of Sinai
