Considering as Christ promised to send the Holy Spirit to the church I can only imagine someone who is from an un-Christian Sect or who beleives Christ lied could suggest that when represenatives from the entirety of the church come together with thousands of priests and laity to consider important matters to the church that the Holy Spirit would not be right their keeping them on the strait and narrow.
i DON'T know.
Were there 'tongues and interpretations' at such meetings?
Or was Holy Spirit's evident presence in His still small voice role.
I don't see Him standing over many church council meetings with a ball bat.
Politics can often shove Him aside quite effectively.
Witness the Anglican/Episcopal homosexual travesty.
