Meditation of St. Francis of Assisi on the Most Blessed Sacrament

In a letter to his brother friars, St Francis writes that one should not hold anything back.

Let everyone be struck with fear,
the whole world tremble,
and the heavens exult
when Christ, the Son of the living God,
is present on the altar in the hands of a priest!
O wonderful loftiness
and stupendous dignity!
O sublime humility!
The Lord of the universe,
God and the Son of God,
so humbles Himself
that He hides Himself
for our salvation
under an ordinary piece of bread!

See the humility of God, brothers,
and pour out your hearts before Him.
Humble yourselves
That you may be exalted by Him.
Hold back nothing of yourselves for yourselves,
that He Who gives Himself totally to you
may receive you totally!
