That tells you about PC USA. Which is a historical mainline liberal presbytery in the US. It doesn't tell you in the last 5 years a good number of individual congregations have left because of this very issue and emigrated to the EPC or other slightly 'less' liberal denominations. Or that PCUSA has been hemmoraging numbers for a long time. Or the PCUSA has often been thought of as a big umbrella denoms that has in the past allowed individual prebyterys (regionally) to have differing rules.

Or that presbyteries are not like catholic churches or anglican ones! There are no priests or higher authorities! Each presby congregation is made up of members, who elect elders, who then visit their local presbytery (the regional org) to vote on matters.

Most importantly, it misses the fact, that Presbyterian is an anagram for Britney Spears
