Saint Faustina wrote:
"Our meals shall be such that not even the poor will have any reason to envy us" (546). So, it's no surprise that St. Faustina didn't eat meat on Fridays even outside of Lent. That was Canon Law. But since St. Faustina's time, Canon Law has allowed us, depending on our bishops conferences, to choose another penance on Fridays in place of abstaining from meat. The United States Conference of Catholic Bishops allow a substitute penance. Nevertheless, the USCCB gives "first place to abstinence from flesh meat" (24, Pastoral Statement on Penance and Abstinence)
Write that by day and by night My gaze is fixed upon him and I permit these adversities in order to increase his merit.
Jesus, Friend of a lonely heart, You are my haven, You are my peace. You are my salvation, You are my serenity in moments of struggle and amidst an ocean of doubts. ...
Jesus said: Do not be absorbed in your misery — you are still too weak to speak of it — but, rather, gaze on My Heart filled with goodness, and be imbued with My sentiments. … when you feel your strength failing, if you come to the fountain of mercy to fortify your soul, you will not grow weary on your journey (Diary, 1486).
