Spiritual Communion is becoming more and more habitual as we grow accustomed to the lack of publicly celebrated Masses. We can more easily make this practice a frequent habit by memorizing a Spiritual Communion prayer.
I wish, my Lord, to receive you
with the purity, humility, and devotion
with which your most holy Mother received you,
with the spirit and fervour of the saints.
