Wondering what I can do for the people of Ukraine,
I have found the following prayer on the internet:
Prayer to Saint Michael
Blessed Michael, archangel,
defend us in the hour of conflict.
Be our safeguard against the wickedness and snares of the devil
(may God restrain him, we humbly pray):
and do thou, O Prince of the heavenly host,
by the power of God thrust Satan down to hell
and with him those other wicked spirits
who wander through the world for the ruin of souls.
