Pope Leo XIV has called on all Christian denominations worldwide to celebrate together the year 2033, marking 2,000 years since Christ's redemption, while receiving a delegation from the Ecumenical Patriarchate of Constantinople. This unprecedented push for global Christian unity under Rome's leadership is a significant prophetic signal, as Scripture warns of a coming false religious unity and a one-world church system in the last days. Revelation 17 and Matthew 24:24 caution believers to test all movements against Scripture, as end-times deception will come cloaked in spiritual language.
