Today begins a week of prayer for Christian unity (January 18-15). It is a worthwhile endeavor and I encourage any who care about Christ and his Church to make this a priority in your prayers this week.
O God, the Father of our Lord Jesus Christ,
our only Savior, the Prince of Peace:
give us grace seriously to lay to heart
the great dangers we are in by our unhappy divisions.
Take away all hatred and prejudice,
and whatever else may hinder us
from godly union and concord;
that, as there is but one body and one Spirit,
one hope of our calling,
one Lord, one faith, one baptism,
one God and Father of us all,
so we may henceforth be all of one heart and of one soul,
united in one holy bond of peace, of faith and charity,
and may with one mind and one mouth glorify you;
through Jesus Christ our Lord.
