As Jesus is the cornerstone upon which the Church is built, so are his teachings the unifying cornerstone of Christian doctrine.
The Parable of the Talents (Matthew 25:14-30) does not seem to cover all possible scenarios. For instance, what if a servant did not bury his talent but lost it to bad investments? This parable is not talking about worldly money but spiritual capital. Heaven’s investments cannot fail because they are the currency of a kingdom which cannot fail. The only way to failure is to do nothing, to bury the gift of God in the ground. If used, it will produce fruit. What if a servant was given a large sum and decided to steal it and run? Again, we are not talking about a worldly master here but God and his kingdom. There simply is nowhere to run from God. The only thing that we can do with spiritual gifts received is either use them or bury them.
