Work (on top of the very inconvenient loss of my wallet and contents) has been very stressful of late, and I am feeling quite off; to-morrow, at suggestion of others, I'm seeing my doctor and having a "mental health day".
Ira furor brevis est: anger is a brief madness. I have a short temper, but that is a passion I ought be overcoming by growing in virtue, bridling it and subjecting it to right reason, rather than slothfully taking the downward path.
"Man's anger worketh not the justice of God" (James i, 20), and such ire is a sure symptom of pride, the root of all evil, and enemy to Christian humility - which, after all, is but the recognition of our true, lowly place in the scheme of things; whereas to be puffed up with overestimated worth is a very madness.
Please of your charity pray that I obtain the patience I need, since I should wish rather to be united with Christ upon His Cross than - mea maxima culpa - more securely nail Him to it.
Prayer against anger
from the Cœleste Palmetum of Wilhelmus Nakatenus (1617-1682)
Should man reserveth anger for his fellow man and yet seek remedy from God? Should he that hath no mercy on one like himself entreat God for his own sins? Who shall obtain pardon for his sins? (Eccli 28:3-5) By these words Thou hast spoken to me though Thy servant Sirach, O Lord God. And after this dare I foster anger and hate against anyone? Spare me, O Lord, spare me of my malice and stubbornness in which I have persevered even unto now. From my soul I now overlook and forgive whatever anyone has done against me. I humbly beg Thee, O Lord, do not rebuke me in Thy fury, nor chastise me in Thine anger. (Ps 37:2) O how would that I be like the deaf who does not hear and the mute who does not speak (Ps 37:14) whenever my enemies rise up in force against me, and those who seek my soul use violence. (Cf. Ps 37:12c) Do not forsake me, O Lord my God, do not depart from me (Ps 37:22), for Thou art my patience. (Ps 70:5a)
Another collection of prayers I make use of is an old High Church Anglican compilation by Oldknow & Crake, as revised by Briscoe: The Priest's Book of Private Devotion...
O Lord, who art slow to wrath, ready to pardon, and of great kindness, remove from me all causeless and immoderate anger, all pride and prejudice, and too much concern for the things of this world, all intemperate speeches and undue excitement. Give me, O God, a mild, peaceable, and humble spirit, that, remembering my own infirmities, I may bear with those of others:... that I may think lowly of myself, and not be angry when others also think lowly of me: that I may be patient towards all men, gentle and easy to be entreated: that thou, for Christ's sake, mayst be so towards me. Amen.
