But it is asserted that Christ built His church on one flawed (as are we all) human being, rather than on the profound, foundational core of TRUTH which that flawed man has just finished confessing, namely, Who and What Christ is.
The Church is Christ's bride (Ephesians 5:29) and has "no spot, wrinkle or blemish" (Ephesians 5:27). Christ also stated that the gates of Hell will not prevail against His Church (Matthew 16:18) so how can the Church commit error? Individual clergy may commit sins, even popes commit sins because in the Church there are both "weeds and wheat" (Matthew 13:30). In its 2000 year history, despite a few bad popes, not one pope ever erred in matters of faith or morals.
