O bringer of light to many nations, you who struggled on for the souls placed in your care that all might know the Christ for whom you toiled, endlessly seeking to convert obstinate hearts – may your zeal inspire missionaries this day to go forth selflessly proclaiming the Gospel to all, bearing witness to the Lord in the cross they bear in season and out of season; whether producing much fruit or being rejected, may their hearts be set on the Word and the love of God for His children. Pray especially those lands you led to Christ will turn again to the one true light.
