Holiness: Unity with the Roman Catholic Church?

Alastair has written a trenchant piece entitled Are Roman Catholics our Brothers?

"The purity of the Church is not an inherent purity. The purity of the Church results from the fact that it belongs to Jesus Christ. If we seek to look for the purity of the Church within the Church itself we will soon settle for a lowered standard of purity, achieved by disowning those we deem to be corrupt."

I highly recommend reading it.
