“The greatest of these is love!” (1 Cor 13:13)
Each Christian has his or her own gifts and vocation in the Church. But it is love alone that gives life to our vocation and makes it bear fruit. This verse, which I have chosen as a motto for my priestly ministry, designates the priesthood as a service of love, a ministry springing from love and aiming at love. As a priest I am called to make visible the saving love of Christ in the Christian community, to accompany and assist all in living their vocation to love.
I can find no other summary of Christianity than 'Love'.
It is the fuel and stamina of any vocation!
