means above all the new commandment, the first
and the greatest of the commandments, and the
one that best identifies us as Christâs disciples:
âThis is my commandment, that you love one
another as I have loved youâ (
Jn
15:12). Clearly,
whenever the New Testament authors want to
present the heart of the Christian moral message,
they present the essential requirement of love for
oneâs neighbour: âThe one who loves
his neigh-
bour
has fulfilled the whole law⦠therefore love
of neighbour is the fulfilling of the lawâ (
Rom
13:8, 10). These are the words of Saint Paul,
for whom the commandment of love not only
sums up the law but constitutes its very heart
and purpose: âFor the whole law is fulfilled
in one word, âyou shall love your neighbour as
yourself ââ (
Gal
5:14). To his communities Paul
presents the Christian life as a journey of growth
in love: âMay the Lord make you increase and
abound in love for one another and for allâ (
1 Th
3:12). Saint James likewise exhorts Christians to
fulfil âthe royal law according to the Scripture:
You shall love your neighbour as yourself â (2:8),
in order not to fall short of any commandment.

sponse and growth is always preceded by Godâs
gift, since the Lord first says: âBaptize them in the
nameâ¦â (
Mt
28:19). The Fatherâs free gift which
makes us his sons and daughters, and the priority
of the gift of his grace (cf.
Eph
2:8-9;
1 Cor
4:7),
enable that constant sanctification which pleases
God and gives him glory. In this way, we allow
