Separation overdue: The PCUSA and homosexuality

This year's (2014) General Assembly of the mainline PCUSA has produced a "church" body that has decided to endorse homosexual "marriages." The news is very sad, but what else can we expect from a denomination that has long turned its back on the Word of God?

The issue I have is with the conservatives (relatively) who had remained in the PCUSA all these years. How much longer can they take this sort of behavior that grieves the Holy Spirit? You speak about reform, yes, it would be great if the denomination repents of all their sins for the last 100 years or so, in sackcloth and ashes. But how long should you wait before you become guilty of dragging God's name through the mud through abetting their crimes?

Ever since the unbiblical defrocking of J. Gresham Machen, there have been people like Clarence Macartney (a conservative PCUSA minister at the time of Machen) who have decided to stay in the PCUSA to reform her. Now that by itself is fie; there is nothing inherently wrong with staying in a denomination to reform it. But the task of reformation implies action, and the sad fact is that these conservatives in the PCUSA weren't actually doing much to reform the denomination at all. Unlike Machen, they did not continually press charges against heretics or speak boldly and loudly against the compromises around them. Instead, they kept rather silent. But let's ignore what they have done to attempt to reform the church. The more important question is: How long have the conservatives been waiting, while the situation in the denomination has only gone from bad to worse? 100 years of growing apostasy, and there has not been even one reversal towards orthodoxy. What does this tell us?

Those who are relatively conservative in theology are normally a majority. They are just moderates in terms of a optimistic view of reforming the church. But if all of them leave the church, it's unlikely the liberals will be able to survive financially for long. In other words, it's the (relative) conservatives who prop up the church. Does this not make them liable to the charge of abetting the liberals?

I'm all for church reform, but give me one reason why heresy should be tolerated in the name of "reform," because I don't see that in Scripture.
