For Paul, his apostolic ministry truly was not simply the chief work of his life, but life itself. In this, however, there was nothing surprising, if we remember what the life of a Christian in general and the life of an apostle in particular are.
The life of every Christian becomes witness from the very moment he becomes a Christian. Strictly speaking, it cannot be otherwise: a Christian is a person of the Kingdom, and it is impossible to live in the Kingdom and hide it. But the ministry of an apostle consists in the fact that he is not only a person of the Kingdom, but also a person of the Church. Of course, this can be said of every Christian, but the chief and only task of an apostle is precisely the building up of the Church as the body of Christ. And such a task is inseparable from constant communication with the people who came into the Church through you. This, as we can see, is what Paul does throughout his life. He does not stay anywhere for long, because the task of an apostle is not the task of the one who presides over a church assembly or of a church administrator; the task of an apostle is spiritual support for individual people and church communities that need such support.
At the same time, the ministry of an apostle is also a visible manifestation of the unity of the Church, not only at the level of a particular church community, but also at the level of the Church as a whole. As is known, in the earliest Christian period, as also in the early Christian period, the Church was a community movement and managed quite well without a rigid centralized structure. In the earliest Christian period, the Church had a council of elders, or presbyters, which handled church-wide matters. But the connection between separate church communities at the grassroots level was carried out precisely by the apostles. Strictly speaking, the Church, for example at the first council in the history of the Church, was represented by apostles and presbyters: the former as people who knew the church situation, as people say, firsthand, and the latter as the most authoritative representatives of church communities. It is no accident that Paul speaks of his desire someday to come to his fellow believers and bring their faith to fullness: for an apostle this was the most natural task. This is how the early Christian Church lived, relying not on structures created by human beings, but on ministers sent by God, who helped it remain the body of Christ.
