The fire that on the Magi's altars glowed
Spake to his soul in symbols and expressed
The immortal purity that without rest
Strives with the mortal grossness whose abode
Is in the heart. Their symboled fire showed One
Whose spirit on the altar of the world
Burns ceaselessly,--where, if all vice be hurled,
It shall be purged with fire that shall atone,--
Christ's love the flame, man's sin th' alchemic stone.
