The idea that “religion was created to control people” basically assumes that there is no God, or that God has not revealed himself or his will to man, both are premises that Christians reject outright. We believe that there is in fact a God, and that God has revealed himself to his people, and that as part of the revelation of himself and his will, he has given us orderly guides for worship in order for his people to remember what God has done for them.
In the Old Testament for example, we see that God revealed himself to Moses, appearing in the burning bush, and delivered his people from the hand of pharaoh. That after delivering his people from pharaoh he came to the Israelites in person and gave them his law for how they should live and worship. As part of this law he stipulated the proper means of worship, forbid the use of idols, instituted the sacrificial system as a means of grace for demonstrating to his people that he forgives their sin, and giving them a liturgical calendar reminding them of the great acts of deliverance and provision that God granted his people. They celebrated holidays such as Rash Hashanah, and First Fruits to remember that God provides for his people. They celebrated holidays such as the feast of tabernacles, and Passover to demonstrate how God delivered and sustained his people. They received Yom Kippur to remind them of their sin and the atonement that God provides. He gave them the Sabbaths to remember God in creation and to provide for the meditation on his word. He provided a priesthood to minister by word and execution of the sacrificial system to teach, instruct, and remind the people of God’s promises to them.
In the New Testament, God came in the flesh. He instituted baptism and the sacrament of the altar as means of grace to deliver his promises of redemption from sin, death, and the devil. We similarly instituted religious holidays mirroring these Old Testament events of deliverance reminding of the deliverance we have through Christ. We instituted Advent and Christmas to celebrate the incarnation of the Son. We instituted Lent to remind us of our sin, and subsequently of Holy Week and the season of Easter to remind us that Christ has defeated sin and death. We instituted Pentecost as a reminder that the Lord has provided us with the outpouring of the Holy Spirit who brings us to faith, sustains us in the faith, leads, guides, and instructs his people through the faithful ministering of his Word and sacraments. We were provided the office of Holy Ministry to faithfully deliver those means of grace and we celebrate the deliverance each Sunday on the Lord’s day.
These things are not meant to “control” us, but to keep His Word and His Promises ever in our view that we might know the great deliverance we have received through Jesus Christ, our Lord, and that it might form us in faith and guide us in our walk before God. If you think that is controlling then maybe you are doing it wrong, or you are worshipping the wrong god.
