Instruction in Christian truth gives meaning and content to the celebrations and fulfills an important part of their original purpose. In essence, observance of the Lord's Day is a celebration. It is a joyful commemoration of Christ's victory over sin and death. Other Christian celebrations also involve gift-giving, either among ourselves or to the needy. Christ has conquered, and his people should rejoice.
Human beings have a natural desire to celebrate important events and turning points in life.
We celebrate victories in war, victories in athletics, birthdays, wedding anniversaries, and anniversaries of all sorts. The degree to which we celebrate an event is the degree to which we honor the person, relationship, or institution which the event signifies. If we value those events that effected our salvation, then we should honor them with appropriate festivity. As human beings we are going to celebrate, even as we are going to establish routines and customs. Given that this is the case, let us celebrate with the greatest jubilation those realities which form the basis of our Christian life.
