212 We should not think of this mission of sharing Christ as something only between Jesus and me. Mission is experienced in fellowship with our communities and with the whole Church. If we turn aside from the community, we will be turning aside from Jesus. If we turn our back on the community, our friendship with Jesus will grow cold. This is a fact, and we must never forget it. Love for the brothers and sisters of our communities – religious, parochial, diocesan and others – is a kind of fuel that feeds our friendship with Jesus. Our acts of love for our brothers and sisters in community may well be the best and, at times, the only way that we can witness to others our love for Jesus Christ. He himself said, “By this everyone will know that you are my disciples, if you have love for one another” ( Jn 13:35).
