So koinonia / communio is a foundational term which gained fundamental significance for the early church, and which in the eyes of many once more occupies a pre-eminent place in defining the essence of the Church today. The Church is shared participation in the life of God, therefore koinonia with God and with one another (1 Jn, 1,3).
So from the beginning the episcopal office was ‘koinonially’ or collegially embedded in the communion of all bishops; it was never perceived as an office to be understood or practised individually. In his history of the Church Eusebius describes in detail the endeavours to maintain peace, unity, love and communion during the violent conflicts of the second century regarding the correct fasting practices and the dating of Easter (Hist. eccl., v,23f; cf. vii,5). The collegial nature of the episcopal office achieves its most impressive expression in the consecration of bishops.
‘The episcopate is one, each part of which is held by each one for the whole’ (Cyprian of Carthage De ecclesiae catholicae unitate, 1,5). Such statements and admonitions recur again and again in Cyprian’s letters (Ep., 55,21; 59,14 et al.). Most familiar is the statement that the Church is the people united with the bishop and the flock devoted to its shepherd. ‘The bishop is in the church and the church is in the bishop, and if anyone is not with the bishop he is not with the church.’ But Cyprian goes even one step further: he not only emphasises the unity of the people of God with its own individual bishop, but also adds that no one should imagine that he can be in communion with just a few, for ‘the Catholic Church is not split or divided’ but ‘united and held together by the glue of the mutual cohesion of the bishops’ (Ep., 66,8).
