Shemini

Investiture's complete; it's been a week,
These Cohanim are ready to debut.
They've learned to dress, and schecht, and not to speak.
(as grievous as that last feels for a Jew) 
White-clad in linen, purged of sin and fear,
a turban knotted on each oil-slicked head
uniquely set apart, prepped to draw near,
a fancy-dress rehearsal to play dead.
As pure as Aaron's bull, and just as game
as Isaac, when his father'd raised that knife,
these two found consummation in the Flame,
exultant as a groom to take a wife.
Saint Paul proposed salvation's won through Faith;
Jews partner God, and have done, since the Eighth.
