Several traditions within the Christian church have understood the second commandment differently. Some have understood it is a prohibition against statues. Others understand the commandment to prohibit images of God in worship. Still others argue it is a prohibition against all images as representations of God. We discuss the duties required and reasons annexed to the second commandment as well as the liturgical theology inherent to the issue.

Westminster Confession of Faith, Chapter 21: Of Religious Worship, and the Sabbath Day

1. The light of nature showeth that there is a God, who hath lordship and sovereignty over all, is good, and doth good unto all, and is therefore to be feared, loved, praised, called upon, trusted in, and served, with all the heart, and with all the soul, and with all the might. But the acceptable way of worshiping the true God is instituted by himself, and so limited by his own revealed will, that he may not be worshiped according to the imaginations and devices of men, or the suggestions of Satan, under any visible representation, or any other way not prescribed in the Holy Scripture.
