I believe this is what you are asking for. Here are 3 prayers specifically for the Church:
I pray for the Mystical body of Christ, the Church, whose visible head is the Pope. I pray for his health and his intentions, I pray for all the needs of the Church, for an increase in vocations to the religious life and to the Priesthood, for the faithfulness and the holiness of Priests. Amen.
We pray You, O almighty and eternal God! Who through Jesus Christ hast revealed Your glory to all nations, to preserve the works of Your mercy, that Your Church, being spread through the whole world, may continue with unchanging faith in the confession of your name. Amen.
Heavenly Father, look upon our community of faith which is the Church of your Son, Jesus Christ. Help us to witness to his love by loving all our fellow creatures without exception. Under the leadership of the Holy Father and the Bishops keep us faithful to Christ’s mission of calling all men and women to your service so that there may be “one fold and one shepherd.” We ask this through Christ, our Lord. Amen.
