Yesterday was Maundy Thursday, the day Christians remember the Last Supper and the night Jesus was arrested. At the last supper, Christ said "This is my body" and "This is my blood", pointing to how he was about to give his body up for sacrifice and have his blood spilled for his followers. Ever since Christians have celebrated holy communion in remembrance of that night, but there has been debate among branches of Christianity about what is actually going on in that ritual. Some believe that the bread and wine are mere symbols, pointing us to remember Christ's sacrifice. Others believe in a more literal reading of Christ's words, feeling that in some mystical way the bread and wine actually take on the substance of Christ's body and blood, either at the point of blessing (transubstantiation) or in some way at all times (consubstatiation). This communion scene was on Pinterest; it was attributed to ValGlaser on Etsy, but that person seems to have deleted their Etsy account, so I don't have a link to the original.
