The attributes of God in Christian theology are those characteristics of God discussed in the Bible.
Many Reformed theologians distinguish between the communicable attributes (those that human beings can also have) and the incommunicable attributes (those that belong to God alone). Donald Macleod, however, argues that "All the suggested classifications are artificial and misleading, not least that which has been most favoured by Reformed theologians - the division into communicable and incommunicable attributes."
Many of these attributes only say what God is not - for example, saying he is immutable is saying that he does not change. The attributes of God may be classified under two main categories:
The Westminster Shorter Catechism's definition of God is merely an enumeration of his attributes: "God is a Spirit, infinite, eternal, and unchangeable in his being, wisdom, power, holiness, justice, goodness, and truth." The Westminster Larger Catechism adds certain attributes to this description, such as "all-sufficient," "incomprehensible," "every where present" and "knowing all things". This answer has been criticised, however, as having "nothing specifically Christian about it."
