Retired Pope Benedict XVI said dialogue with other religions is no substitute for spreading the Gospel to non-Christian cultures, and warned against relativistic ideas of religious truth as “lethal to faith.” He also said the true motivation for missionary work is not to increase the church’s size but to share the joy of knowing Christ.
In other words, dialoguing with the world and other religions and sects is not a substitute to converting others to the truth of Christianity. St. Paul wanted to convert everyone to Christ. We should do the same. Dialogue is great, but not for dialogue’s sake. The goal is to bring everyone to the joy of knowing Christ.
