In the biblical context, altars serve as significant structures for worship, sacrifice, and communion with God. The mention of "altars of brick" is found in Isaiah 65:3, where God expresses His displeasure with the rebellious practices of the Israelites: "These people continually provoke Me to My face, sacrificing in gardens and burning incense on altars of brick" . This reference highlights the deviation from prescribed worship practices, as altars of brick were not in accordance with the instructions given by God for altar construction.

Biblical Context and Significance

The construction of altars in the Old Testament was a matter of divine instruction. In Exodus 20:24-25, God commands the Israelites to make altars of earth or uncut stones: "You are to make an altar of earth for Me and sacrifice on it your burnt offerings and peace offerings, your sheep and goats and cattle. In every place where I cause My name to be remembered, I will come to you and bless you. If you make an altar of stones for Me, you must not build it with cut stones, for if you use a chisel on it, you will defile it" . The use of natural, unhewn materials symbolized purity and obedience to God's commands.

Deviation and Rebellion

The use of brick for altars, as mentioned in Isaiah 65:3, signifies a departure from these divine instructions. Brick, a man-made material, represents human innovation and effort, contrasting with the God-ordained simplicity and naturalness of earth and uncut stones. This deviation is emblematic of the broader spiritual rebellion of the Israelites, who were engaging in idolatrous practices and syncretism, blending the worship of Yahweh with pagan rituals.

Theological Implications

Theologically, the use of altars of brick can be seen as a metaphor for the Israelites' self-reliance and disobedience. By choosing their own methods of worship, they were effectively rejecting God's sovereignty and authority. This act of rebellion is further emphasized in Isaiah 65, where God lists the various ways His people have turned away from Him, culminating in His pronouncement of judgment and the promise of a new creation for those who remain faithful.

Symbolism and Lessons

From a symbolic perspective, altars of brick serve as a cautionary example of the dangers of departing from God's instructions. They remind believers of the importance of adhering to divine commands and the perils of allowing human wisdom to supersede God's revealed will. The narrative underscores the necessity of worship that is both obedient and faithful, rooted in the acknowledgment of God's holiness and authority.

In summary, the mention of altars of brick in the Bible serves as a poignant reminder of the consequences of disobedience and the importance of maintaining purity in worship. It calls believers to reflect on their own practices and to ensure that their worship aligns with the principles and commands set forth by God.
