… whenever Christ, the Bridegroom of pure souls, is mystically united with each soul, He gives the Father occasion to rejoice over this as at a wedding. It is Christ Himself Who says, ‘Joy shall be in heaven over one sinner who repents’ (Lk. 15:7). For joy, according to the Apostle, is the fruit of the Holy Spirit (Gal. 5:22), Who through conversion brings back to Christ those living in repentance, and reunites them with Him. And this joy embraces both those in heaven and godly men on earth. That is why there is joy in heaven over one repentant sinner.
