Sam Barnett-Cormack brings a grammarian’s eye to our use of the old Quak­er phrase, “The Things Which Are Eternal”:

To know one anoth­er in that which is eter­nal is to share our grace, our Light, our spir­i­tu­al expe­ri­ence. It goes beyond the sort of know­ing that might come from social activ­i­ties and ice­break­ers; indeed, it is of an entire­ly dif­fer­ent char­ac­ter… For it comes down to this – to know one anoth­er in that which is eter­nal is to know the Divine, and to know the Divine is to know one anoth­er in this way; they are two sides of one coin, and we can only pro­mote one by also pro­mot­ing the other.
