2 Cor 6:1-10 / Matthew 5:38-42
The fundamental and basic truth of Christianity can be expressed quite simply - love God and love neighbour.
That is also what Jesus said in the gospel when He was asked which is the greatest commandment of all (Mt 22:36-37 / Mk 12:30-31 / Lk 10:27)
But what can be expressed simply may not necessarily mean that it can be accomplished so easily, as we heard in today's gospel passage.
Among other things, this is what Jesus taught : offer the wicked man no resistance; if someone hits you on the right cheek, offer him the other as well; if anyone orders you to go one mile with him, go two miles with him, etc.
That seems to be the high end of Christianity and certainly quite difficult to achieve.
But before we think about trying to attain the advanced stage of Christian discipleship, it would be better to know what is the basic requirement.
The 1st reading states among other things these basic qualities - purity, patience, kindness, holiness.
Let us ask the Lord to grant us the grace to attain these basic qualities as a disciple.
So that in all that we do we will live out the fundamental and basic truth of Christianity - to love God and to love neighbour.
