Pope Leo XIV sent a video message endorsing 'Thy Kingdom Come', a global ecumenical prayer movement now active across 85 Christian denominations in nearly 90% of nations worldwide. The event represents a significant step in the merging of historically divided Christian traditions under unified leadership and vision — a pattern Scripture associates with the emergence of a consolidated false religious system in the last days. Revelation 17 describes a global religious authority operating in concert with political power, and the accelerating institutional unity of world Christianity under papal direction is a marker of that trajectory.
