The early Church's unanimity in prayer
Cyprian is describing the unity of the early believers under the apostles, before he contrasts it with the decline of his own time.
This unanimity once existed under the apostles. So the new people of believers, keeping the Lord's commands, held fast to its love. Scripture proves this when it says: "The crowd of those who had believed acted with one soul and mind" (Acts 4:32). And again: "They were all persevering with one mind in prayer, together with the women and Mary the mother of Jesus and his brothers" (Acts 1:14). That is why they prayed with effective prayers; that is why they were able to obtain with confidence whatever they asked from God's mercy.
Latin
. Haec unanimitas sub apostolis olim fuit: sic nouus credentium populus Domini mandata custodiens caritatem suam tenuit. probat scriptura quae dicit: turba autem eorum qui crediderant anima ac mente una agebant. et iterum: et erant perseuerantes omnes unanimes in oratione cum mulieribus et Maria quae fuerat mater Iesu et fratribus eius. et ideo efficacibus precibus orabant, ideo impetrare cum fiducia poterant quodcumque de Dei misericordia postulabant.
