Frequently Asked Questions

Q: What about leavening agents found in cleaning products and water?

A: True Spirit of Christ's position regarding keeping leavening agents that are used to clean as brush teeth is they are still allowed according to the law.

Exodus 12:19
Seven days shall there be no leaven found in your houses: for whosoever eateth that which is leavened, even that soul shall be cut off from the congregation of Israel, whether he be a stranger, or born in the land.

Water - If you have water that has one of the ingredients above in it, you can still keep it in your home. These ingredients are not being used as an active leavening agent within your water.

Toothpaste - If you have toothpaste with certain ingredients above in it, you can still keep this product in your home, because this is not a food product used for baking/cooking, and the ingredient within the toothpaste is not being used as an active leavening agent.

If you find within your spirit you would like to still throw these items away as personal preference please feel free, just understand the law is referring to food/baking products we would consume.
