I came across this prayer in a book recently and found it incredibly profound:

O God, you are the fountain of all truth; we ask you to protect your church from all false teaching.
Protect the Church
From all teaching and preaching which would destroy men’s faith;
From all that removes old foundations without putting anything in their place;
From all the confuses the simple,
that perplexes the seeker,
that bewilders the way-faring man.
And yet at the same time protect the Church
From the failure to face new truth;
From devotions to words and ideas
which the passing of the years has rendered unintelliglble;
From all intellectual cowardice
and from all mental lethargy and sloth.
O God, send to your Church teachers,
Whose minds are wise with wisdom;
Whose hearts are warm with love;
Whose lips are eloquent with truth.
Send to your Church teachers
Whose desire is to build and not to destroy;
Who are adventurous with the wise,
and yet gentle with the simple;
Who strenuously exercise the intellect,
and who yet remember that the heart has reasons of its own.
Give to your Church preachers and teachers who can make known the Lord Christ to others because they know him themselves; and give to your Church hearers, who, being freed from prejudice, will follow truth as blind men long for light. The we ask through Jesus Christ our Lord. Amen.
