Sabbath Rest and Mutability in Spenser's Epithalamion

Edmund Spenser's Epithalamion--while it is a love poem and marriage ode--is also curiously connected to the idea of sabbath rest and Spenser's pervasive concern with mutability. While his Mutability Cantos, written near the end of his life, give full voice to expressing the pain mutability inflicts, Epithalamion, also written near the end of his life, seems to suggest a solution, at least a partial one.
