We have been praying the following prayer together for at least 13 centuries. Whilst it is still used in the RC Extraordinary Form, I have been unable to find it in the Ordinary Form (help me?).
You can read more about it in the commentary: Collect for Lent 3
Let us pray (in silence) [that the more we see that we have no power of ourselves to help ourselves, the more we may be drawn closer to God]
pause
God,
the source of all our strength;
watch over us within and without,
that in body we may be protected from all adversity,
and in mind cleansed from all destructive thoughts;
through our Saviour Jesus Christ,
who is alive with you and the Holy Spirit,
one God now and for ever.
Amen.

Could you recommend to me a source where I can find proper prefaces for each Sunday
Lakshman, I do not know what your tradition is or the format for the Eucharistic Prayer you use into which you wish to insert a proper preface – do you mean the sort of preface found, say, in the Book of Alternative Services? Blessings.
