Anger can be a spiritual response to our personal connection with injustice

Matthew 21 12 Jesus went into the temple and chased out everyone who was selling or buying. He turned over the tables of the moneychangers and the benches of the ones who were selling doves. 13 He told them, “The Scriptures say, ‘My house should be called a place of worship.’ But you have turned it into a place where robbers hide.”
14 Blind and lame people came to Jesus in the temple, and he healed them. 15 But the chief priests and the teachers of the Law of Moses were angry when they saw his miracles and heard the children shouting praises to the Son of David.[e] 16 The men said to Jesus, “Don’t you hear what those children are saying?”
“Yes, I do!” Jesus answered. “Don’t you know that the Scriptures say, ‘Children and infants will sing praises’?” 17 Then Jesus left the city and went out to the village of Bethany, where he spent the night.
Prayer
from origen (184-253 CE)
Let us pray, however, the mercy of the omnipotent God to make us not only hearers of the word, but also doers and to bring upon our souls also a flood of God’s water and destroy in us what God knows should be destroyed, and encourage what God knows should be encouraged, through Christ our Lord and through the Holy Spirit. To God be glory forever and ever. Amen.
Egeria in the Holy land, c. 380 CE
Egeria was a nun from France who was touring the Holy Land in the late 4th century. She was in Jerusalem during Holy Week and provides the only eye witness account of how the early church celebrated.
On Monday, the following day, they carry out in the Anastasis (rotunda built on site assumed to be Christ’s tomb) whatever ceremonies are customarily performed from the first cockcrow until dawn, as well as whatever is done at the third and sixth hours throughout Lent. However, at the ninth hour everyone comes together in the major church or Martyrium, and until the first hour of the night they continually sing hymns and antiphons, and read passages from the Scriptures fitting to the day and the place, always interrupting them with prayers. Vespers is celebrated in the Martyraim, when the hour for it is at hand. The results is that it is already night when the dismissal is given at the Martyrium. As soon as the dismissal has been given, the bishop is led from there to the Anastasis to the accompaniment of hymns. When he has entered the Anastasis, a hymn is sung, a prayer is said, first the catechumens and then the faithful are blessed, and finally the dismissal is given.
