sedes mis-think the term 'infallible'.. sedes interpret 'infallible' as meaning 'without blemish'..But thats not at all what Christ prominsed about His Church..He specifically said He wouldnt correct our path from Heaven but that regardless of our decisions made, His Church would survive and be there unto the very end of time and His return..Thats Christ's definition of 'Infallible'..meaning: the Gates of Hell cannot snuff out His Church..
