For love of God, cheerfully endure everything — labour, sorrow, temptation, provocation, anxiety, necessity, weakness, injury and insult; censure, humiliation, disgrace, contradiction and contempt. All these things foster your growth in virtue, for they test the unproved servant of Christ, and form the jewels of his heavenly crown.

[Pro amore Dei debes omnia libenter subire , labores scilicet et dolores, tentationes et vexationes, anxietates et necessitates , infirmitates , injurias, oblocutiones , reprehensiones, humiliationes, confusiones, correctiones et despectiones. Haec juvant ad virtutem , haec probant Christi tironem, haec fabricant coelestem coronam.]
