Today, the baptism by John in the Jordan still recent, we should all remember the kind of conversion of our baptism. We have all been baptized into one Lord, into one only faith, «For we were all baptized by one Spirit into one body» (1Co 12:13). Here we have the ideal of unity: to form a single body, to be a single unity in Christ, so that the world may believe.
In today's Gospel we see that «A large crowd from Galilee followed him» and also «a great number of people» coming from other places (cf. Mk 3:7-8) are surrounding the Lord. And He paid heed to all procuring, without exception, their good. We have to keep this in mind during the Octave of Prayer for Christian Unity.
Let us realize how, throughout centuries, we Christians have divided ourselves into Catholics, Orthodox, Anglicans, Lutherans and a long etc. of Christian confessions. A historic sin against one of the essential points of our Church: its unity.
But, let us face today's eclesial reality. Our bishopric's, our parish's, our Christian group's. Are we really one only thing? Is our type of unity really a motive for conversion of those away from the Church? «that all of them may be one, … so that the world may believe» (Jn 17:21), pleaded Jesus to the Father. This is our challenge. That pagans all over may see a group of believers relate one another, gathering by the Holy Spirit, under the Church of Christ: all the believers were one in heart and mind. (cf. Acts 4:32-34).
Let us remember that, as a fruit of the Eucharist, the unity of the Assembly is to manifest itself along with the union with Jesus of each one of us, as we are fed by the same Bread to be a one and only body. Therefore, what the sacraments stand for, and the grace therein instilled, demand from us gestures of communion towards all others. Our conversion is to the Trinity unit (which is a gift coming from Heaven) and our sanctified task cannot avert the gestures of communion, of understanding, of welcome and forgiveness towards our brothers.
