Prayer for the Holy Trinity

Father, Son and Holy Spirit,
three persons, but one God,
enlighten our hearts and minds,
make us steadfast in the true faith,
equip us for good works,
and bring us to life eternal;
through your mercy, O our God,
you are blessed,
and live and govern all things,
now and forever.
Amen.
