How do we know that the bread and wine are not literally Christ's body and blood?

The assertion that the bread and wine are not literally Christ's body and blood stems from multiple theological considerations. Firstly, the conduct of the disciples during the institution of the Lord’s Supper indicates that they understood His words figuratively. As Jews, they were taught to avoid consuming blood, and there is no indication that they were alarmed by His words. Secondly, our sensory experiences confirm that what we partake in remains bread and wine. Additionally, the doctrine of Christ's human nature affirms that He cannot be physically present in multiple places simultaneously, which further supports the understanding that the words spoken by Jesus are metaphorical rather than literal. This interpretation is consistent with how Jesus often used figurative language in Scripture.
