On the Lord's Supper
"For I received from the Lord what I also passed on to you: The Lord Jesus, on the night he was betrayed, took bread, and when he had given thanks, he broke it and said, "This is my body, which is for you; do this in remembrance of me." In the same way, after supper he took the cup, saying, "This cup is the new covenant in my blood; do this, whenever you drink it, in remembrance of me." For whenever you eat this bread and drink this cup, you proclaim the Lord's death until he comes. -Apostle Paul, To the Corinthians (1.1.23-26)

Churches of Christ understand the Bible to teach that the Lord's Supper is a necessary part of our Sunday assemblies. Historically, the Lord's Supper has its roots in the Passover feast of the Jews (Exodus 12). Jesus and his 12 closest disciples were celebrating the Passover the night Judas betrayed him to the Roman authorities. The Passover celebrated the night God passed over the houses of the Israelites to slay the firstborn children and animals in the homes of their Egyptian slave masters. God bought them that night with the blood of sacrificed lambs. Death happened so that life might be saved from slavery and cruel oppression.
Jesus gave the Passover meal a deeper meaning when he tied it to his sacrifice on the cross to atone for the sins of all people for all time (John 1.29, Romans 5.6-19, 2 Corinthians 5.18-22, etc.). He became God's Passover lamb, and his blood allows God to pass over our sins when we place our faith in him and are baptized to live a new life (see the article from last week).
As the Apostles and other Christians spread the good news about what God had done in Jesus, believers came together on a regular basis and continued to eat a meal to celebrate the event. For instance, when Paul comes to the church in Troas (what is now Turkey-Acts 20.7), the disciples had gathered together to break bread. In Acts, breaking bread often refers to the Passover-like covenant meal celebrating the Lord's sacrifice and return. In fact, the quote from Paul above tells us that the Corinthian church had been taught to observe this meal.
Paul also said, though, that the meal is more than a meal or even a commemorative meal. It has spiritual connotations. It affects us spiritually. If done improperly, i.e. used to separate out groups within the church or used as a license for excess (1 Cor 11.18-21), then the meal actually turns into something that can weaken, sicken, or cause us to "fall asleep" (which is a euphemism for dying). It is not magic cracker and grape juice (in the New Testament it was a meal and not just cracker and grape juice). But when people of faith take it, it becomes something more than cracker and grape juice. For us who believe, it becomes the body and blood of Jesus-the source of our lives.
So, we take it weekly as the early Christians did. We take it on Sunday as the early Christians did because that's the day the Lord was raised from the dead. And we take it to help us remember what price was paid for our salvation, to remember the hope and future God has given us because of that payment, and to remember that we are bound to each other in faith and blood.
So, for the Northside Church of Christ, we will continue to take the Lord's Supper on every Sunday morning and evening we are assembled. Small groups that meet on Sunday evenings will also have the opportunity to take the Lord's Supper together.
