In the fourteenth century St. Bernardine of Siena and St. John of Capistrano used the IHS symbol to venerate the Holy Name of Jesus.
After many miracles, Pope Martin V approved this devotion in 1427 and added the Cross.
St. Bernardine is the reason that the name Jesus was added to the Hail Mary which originates in the Gospel of St. Luke.
St. Paul says: "That in the name of Jesus every knee should bow.... And that every tongue should confess that the Lord Jesus Christ is in the glory of God the Father." (Philipians 2:10-11)
