The Lord’s Supper is a family meal. What would you think of a family which didn’t allow their adopted children to eat dinner with the family? I hope we would all condemn them and probably excommunicate them if they did not repent. But, what if, after they met with the elders, they decided to not serve the adopted children dinner until the adopted children were old enough to decide whether they really wanted to be part of the family? Or, what if they refused to serve the adopted children dinner until they could discern whether the adopted children were really acting like good members of the family? I think we all see the folly of this mindset. The family that eats together stays together. If we want our adopted children to feel like part of the family, we treat them like part of the family. We don’t wait for them to make a decision to join our family. They are a part of our family, and they have right to join us at the family table.
God has adopted us into His family. God feeds us at His table. This is how he builds up his family. He invites us to partake of His Son in faith, through the power of the Holy Spirit. And He invites all of us, including our children. If they are baptized, then they are also His adopted children. If you feed your children at home, then you need to feed them here. But, you can’t feed them here. You need to bring them to the Lord’s Table, where God feeds all of his adopted children.
