In this paper, I explore the traditional religious account of what can make
a life meaningful, namely, the view that one's life acquires significance insofar as
one fulfils a purpose God has assigned. Call this view ‘purpose theory’. In the
literature, there are objections purporting to show that purpose theory entails the
logical absurdities that God is not moral, omnipotent, or eternal. I show that there
are versions of purpose theory which are not vulnerable to these reductio
arguments. However, I then contend that there is a problem facing purpose theory
which no version can avoid. I argue that the best reason for holding a God-centred
theory of life's meaning logically precludes the possibility of purpose theory being
the correct version of it. More specifically, I argue that if a relationship with God is
necessary for one's life to acquire meaning, this must be because God would have
properties such as atemporality and simplicity, perfections which are incompatible
with purposiveness. I conclude that religious thinkers have good reason to develop
other theories of the way God could confer meaning on our lives.
