I came to the Irish people to preach the Gospel and endure the taunts of unbelievers, putting up with reproaches about my earthly pilgrimage, suffering many persecutions, even bondage, and losing my birthright of freedom for the benefit of others.
If I am worthy, I am ready also to give up my life, without hesitation and most willingly, for Christ’s name. I want to spend myself for that country, even in death, if the Lord should grant me this favor.
It is among that people that I want to wait for the promise made by Him, who assuredly never tells a lie. He makes this promise in the Gospel: “They shall come from the east and west and sit down with Abraham, Isaac and Jacob.” This is our faith: believers are to come from the whole world.“
