σημεῖον

Sēmeîon broadly refers to a sign, mark, or indicator. In its most basic sense, it can refer to a distinguishing mark or a signal. However, in the New Testament, it frequently takes on a specialized meaning, conveying events or phenomena that point to a deeper reality, often of divine origin. These signs are not merely spectacular occurrences but are intended to communicate a message, reveal truth, and elicit a response, such as faith or understanding.

Sēmeîon is commonly associated with miracles and wonders, but it is important to note that not all miracles are called sēmeîa, nor are all sēmeîa necessarily miraculous in nature. The key characteristic of a sēmeîon is its interpretive value—it directs attention beyond itself to the one performing the sign or to the truth it embodies. For instance, Jesus’s miracles are often presented as sēmeîa, not simply for their display of power, but because they signify his identity as the Messiah and the coming of God’s kingdom. The Gospel of John, in particular, highlights several of Jesus’s works as "signs," emphasizing their revelatory purpose.

The term can also be used in a negative sense, referring to signs that deceive or mislead, as seen in descriptions of the "signs and lying wonders" of the antichrist. This usage underscores the need for discernment, as not all signs originate from God. Ultimately, the biblical understanding of sēmeîon stresses its function as a pointer to divine activity, both redemptive and, in some cases, deceptive, urging observers to consider its meaning and source.
