About 75% of the individuals within our corporate body attended the barbecue.
So our church had been “predestined” or “elected” to attend the barbecue, unconditionally. Not everyone within our corporate body attended the lunch.
People say that corporate election implies particular election. That is not necessarily the case; not even in regular usage.
“The church” was corporately elected to have lunch at the parsonage. “The church” would be there no matter what. But individuals were invited to attend the lunch and could freely choose to accept or reject the offer. Their individual choice to attend or not would have no impact on the fact that “the Church” would be there.
Corporate election does not necessitate particular election.
