Catholic theologian James Alison:

Spending time, as I do, with people on both sides of the Reformation divide, I find strict parallels between the temptations to which either side is prone. Protestantism is tempted to bibliolatry, and Catholicism is tempted to ecclesiolatry. Both are forms of idolatry that involve some sort of grasping of security where it is not to be found. This grasping ends up by evacuating the object grasped (whether the Bible or the church) of meaning, turning it instead into a projection of the one grasping. The nonidolatrous approach is when we allow ourselves to be reached and held by a living act of communication from One who is not on the same level as either Bible or church, but of whose self-disclosure those realities can most certainly become signs. A sure sign of a pattern of desire locked in grasping is the speed with which we collapse into invidious comparisons such that we acquire our identities over against others in our own group, rather than receiving them together patiently from the one calling us into being.
