Aquinas is da bomb, and that's all there is to it.
If you liked Aquinas, then you will love his Eastern counterpart, St. Ephrem the Syrian.
Saint Ephrem the Syrian Library
O Lord and Master of my life,
take from me the spirit of sloth, despondency,
lust of power, and idle talk;
But grant rather
the spirit of chastity, humility, patience, and love
to thy servant.
Yea, O Lord and King,
grant me to see my own transgressions,
and not to judge my brother;
for blessed art Thou unto the ages of ages.
Amen.
