With zeal and courage Basil opposed the heretics who denied that Jesus Christ was God as Father (cf. Basil, Letter 9, 3: PG 32, 272a; Letter 52, 1-3: PG 32, 392b-396a; Adv. Eunomium 1, 20:PG 29, 556c). Likewise, against those who would not accept the divinity of the Holy Spirit, he maintained that the Spirit is also God and “must be equated and glorified with the Father and with the Son (cf. De Spiritu Sancto: SC 17ff., 348). For this reason Basil was one of the great Fathers who formulated the doctrine on the Trinity: the one God, precisely because he is love, is a God in three Persons who form the most profound unity that exists: divine unity.
In his love for Christ and for his Gospel, the great Cappadocian also strove to mend divisions within the Church (cf. Letters, 70, 243), doing his utmost to bring all to convert to Christ and to his word (cf. De Iudicio 4: PG 31, 660b-661a), a unifying force which all believers were bound to obey (cf.ibid. 1-3: PG 31, 653a-656c).
To conclude, Basil spent himself without reserve in faithful service to the Church and in the multiform exercise of the episcopal ministry. In accordance with the programme that he himself drafted, he became an “apostle and minister of Christ, steward of God’s mysteries, herald of the Kingdom, a model and rule of piety, an eye of the Body of the Church, a Pastor of Christ’s sheep, a loving doctor, father and nurse, a cooperator of God, a farmer of God, a builder of God’s temple” (cf. Moralia 80, 11-20: PG 31, 864b-868b).
This is the programme which the holy Bishop consigns to preachers of the Word – in the past as in the present -, a programme which he himself was generously committed to putting into practice. In 379 A.D. Basil, who was not yet 50, returned to God “in the hope of eternal life, through Jesus Christ Our Lord” (De Baptismo, 1, 2, 9).
He was a man who truly lived with his gaze fixed on Christ. He was a man of love for his neighbour. Full of the hope and joy of faith, Basil shows us how to be true Christians.
