"As many as touched it were healed"
Now if, when Jesus went about in the world, the mere touch of his robes cured the sick, why doubt, if we have faith, that miracles will be worked while he is within us and that he will give what we ask of him since, in eucharistic communion, he is in our house? His Majesty is not accustomed to paying poorly for his lodging if the hospitality is good. If it pains you not to see him with your bodily eyes, consider that seeing him so is not fitting for us...
But our Lord reveals himself to those who he sees will benefit by his presence. Even though they fail to see him with their bodily eyes, he has many methods of showing himself to the soul, through great interior feelings and through other different ways. Be with him willingly; don't lose so good an occasion for conversing with him as is the hour after having received Communion.
Pope Saint Pius X
