The heavenly voice told St. John to write: “I advise you to buy from me white garments to put on, so that your shameful nakedness may not be exposed.” (Revelation 3:18)
Shameful nakedness. That image might remind us of chapter 16 of the book of the prophet Ezekiel. (One of the PG-13 chapters of the Bible.) The Lord speaks to the city of Jerusalem as to a beloved adopted daughter. He found her as an abandoned, unwashed newborn. He cared for her, cleaned her, dressed her, and adorned her with jewelry.
Then she grew conceited. She consorted with many strange lovers. She engaged in abominable sacrileges and exposed herself over and over again.
But even after all this, the Lord had a heart moved with compassion for His beloved adopted daughter, Jerusalem–His people. At the end of Ezekiel 16, the Lord declares, “I will re-establish my covenant with you, that you may remember, and be ashamed, when I pardon you for all you have done.”
Pope Francis remarked that he considered these words addressed directly to him personally. The pope wrote:
For me this is one of the most important revelations: you will continue to be my chosen people and all your sins will be forgiven. Mercy is deeply connected with God’s faithfulness. The Lord is faithful, because he cannot deny himself…You can deny God, you can sin against him, but God cannot deny himself. He remains faithful.
God faithfully keeps His covenant with Abraham, sealed with the Precious Blood of His Son, shed to save sinners.
