In this parable Jesus speaks about a master who returns after a long absence. When the 'master' returns he may find a faithful slave. Or he might find an unfaithful one. If the master finds that his slave was faithful, he will be put in charge of all the master's 'possessions'. If the slave is not faithful, he will assign him to 'a place with hypocrites' where there is much sadness.

Some translations of the Bible use the word 'servant' instead of slave.
With the spirit of God on our side, we have nothing to fear. The Bible says, 'In God I trust, I will not be afraid. What can mortal man do to me?' Psalms 56: 4 NIV
Critics say that trusting in mortal human organization as much as we trust in God, could be a modern day form of idolatry. This certainly seems like a valid opinion based on the scriptures. But doesn't Matthew 24:45-51 prove that God appointed a slave to dispense spiritual food to the world in this time of the end?
Bible scholars have found absolutely no evidence that Jesus or Jehovah appointed a human slave, 'slave class', or religion to feed spiritual food to the world. Let's consider the facts as stated in the Bible by Jesus in Matthew 24:45-51. Read this passage carefully a few times.
Does the Bible say that Jesus and/or Jehovah appointed a slave to dispense spiritual food in these last days before armageddon? If not, then no religion can be God's slave. The Bible says that anyone who runs ahead of what Jesus said does not have God. That is a fact according to 2 John 1: 9 - 11. Rumors about being God's slave are not factual. Critics say that claims of religious superiority is religious propaganda and a form of Mind Control
Jesus said that the 'master' will judge the slave. No one knows who the master is. No one knows who the slave is. Jesus did not mention anything about a slave 'class' or 'spiritual' food. It is not clear what Jesus was trying to teach in Matthew 24:45-51.

The exact meaning of the parable is not known. And since it was a parable or illustration your opinion about what the parable means is just as valid as anyone else's.
Any church or person can claim to be the faithful and discreet slave. Any church can say 'God put us in charge'. Does that mean that it's true? Of course not. Copious amounts of religious propaganda doesn't make any religion better. In fact it's just the opposite.
God does not tell religions what to say or do. He doesn't have a favorite religion. He doesn't pick one religion as the only path to salvation. Religions and people are free to believe whatever they want. Religions can't save people. Only God has the authority to save the people he loves. 'In God I trust, I will not be afraid. What can man do to me?' Psalms 56: 11 NIV
