Biblaridion (βιβλαρίδιον) is the diminutive of biblion, meaning a little book or small scroll. It appears in Revelation 10:2, 8–10 as the "little scroll" held by the mighty angel, which John is commanded to eat. The scroll was "sweet as honey" in his mouth but turned his stomach bitter — symbolizing the bittersweet nature of prophetic ministry.
The eating of the scroll in Revelation 10 directly parallels Ezekiel's scroll-eating (Ezekiel 2:8–3:3) — a common prophetic commissioning motif. God's word must be internalized before it can be proclaimed. The sweetness represents the joy of receiving divine revelation; the bitterness represents the hard, painful content the prophet must declare to the nations. This biblaridion points to the full counsel of God which is simultaneously glorious and sobering. Every preacher of God's word experiences this tension: the gospel is the sweetest news imaginable, yet it includes the reality of sin, judgment, and repentance.
