I found this prayer on a list of prayers on the website of the Cathedral of St. Matthew in Houston, TX. It appears to not be a Catholic Church, unfortunately, but I really like this prayer, although you should read through the rest of their prayers before praying them, of course. You can find the rest of their prayers for wisdom and guidance here. 

Also, don't ever give this church your address. Apparently, they've been accused of a lot of mail scams, which they claim are completely false.

Prayer For Spirit of Wisdom

Father,

you guide your people with kindness

and govern us with love.

Give the Spirit of wisdom

to those you have called to lead your Church.

May the growth of your people in holiness

be the eternal joy of our shepherds.

We ask this through our Lord Jesus Christ, your Son,

who lives and reigns with you and the Holy Spirit,

one God, for ever and ever. 

Amen.

I'm praying for you!

:)
