Whilst researching the last blog entry I came across another ancient hymn to the Holy Spirit called the "Veni Creator Spiritus" and it dates back to the 9th century:
Come, Creator Spirit,
visit the minds of those who are yours;
fill with heavely grace
the hearts that you have made.
You who are named the Paraclete,
gift of God most high,
living fountain, fire, love
and anointing for the soul.
You are sevenfold in your gifts,
you are the finger of God’s right hand,
you, the Father’s solemn promise
putting words upon our lips.
Kindle a light in our senses,
pour love into our hearts,
infirmities of this body of ours
overcoming with strength secure.
The enemy drive from us away,
peace then give without delay;
with you as guide to lead the way
we avoid all cause of harm.
Grant we may know the Father through you,
and come to know the Son as well,
and may we always cling in faith
to you, the Spirit of them both.
A few years back I bought an excellent book of meditations by the preacher to the Papal Household Fr Raniero Cantalamessa recommended, of all people, by Nicky Gumbel Vicar of Holy Trinity, Brompton. It's a wonderful and inspiring read.
