What is the major theme of the poem “The Canonisation”?

Love as immortal and unifying are major themes in this poem. The poet demands that some complainer leave him alone to love. The complainer should turn his attention elsewhere, and nobody is hurt by the love. They are not sinking ships or causing floods, delaying spring or causing others to die, or supporting wars or lawsuits. The poet and his lover take their own chances together; they are unified in their love. They are like candles that will burn out on their own, yet they have been reborn together in fire like the fabled Phoenix. On the other hand, their love is a beautiful example for the world that will be immortalized, canonized, a pattern for all other love in the world.
