Whosoever shall receive one of such little children in my name, receiveth me. Whosoever shall "receive;" that is, show him offices of kindness and charity. One of such little children; that is, such in simplicity, in innocence and humility, such as this little child is in age and stature.
In my Name, that is, with special regard to my Name. He thus seems to link all that is good and beautiful with his Name; as all that is really good and excellent in man is a reflection of his goodness.
St. Luke (Luke 9:48) says, 'Whosoever shall receive this little child in my Name receiveth me." Our Lord, therefore, speaks first, literally of a little child, and secondly, in a mystical sense, of those who are like little children; making that little child in his arms the figure and type of all those who are like little children.
The sense, therefore, of his words is this: "Humility, which is the foundation and the measure of spiritual perfection, so pleases me that I delight in little children. And all who would be my disciples must become as little children, and so will they deserve to be received by all; for men will think that they receive me in them, because they receive them for my sake."
