Unveiling the Word

Understanding Greek words in Biblical studies is essential for uncovering the depth and nuances of Scripture. One such word is Κηφᾶς (Kēphas), a term that holds significant importance in New Testament interpretation. Κηφᾶς is an Aramaic word transliterated into Greek and is most famously used as a name for the Apostle Peter. This name appears in the Gospel of John 1:42 when Jesus meets Simon, son of Jonah, and gives him the name Κηφᾶς, which translates as “rock” or “stone.” The term’s usage in both Greek and Aramaic provides rich insights into the early Christian community’s linguistic and cultural background.

Defining Meanings

The primary meaning of Κηφᾶς is “rock” or “stone.” In the context of the New Testament, it functions more than just a physical rock; it signifies stability, strength, and foundational importance, particularly in reference to Peter’s role in the early church.

Another interpretation centers on its symbolic meaning. By renaming Simon to Κηφᾶς, Jesus is not only giving him a new identity but also a new purpose — to be the foundational leader of the emerging Christian community.

Additionally, Κηφᾶς is often seen as synonymous with Peter, the Greek equivalent of the Aramaic name. Thus, the term has both a literal and metaphorical connotation in the New Testament narrative.

Exploring Similar Words

The Greek word πέτρος (petros) [PEH-tros] is another term for “rock” or “stone” and is closely related to Κηφᾶς. While both mean “rock,” πέτρος is the Greek translation of Κηφᾶς and is used interchangeably with it.

The word λίθος (lithos) [LEE-thos] means “stone” but generally refers to smaller stones rather than a massive rock or boulder. Unlike Κηφᾶς, λίθος does not carry the same symbolic weight in the New Testament narrative.

Another related term is πέτρα (petra) [PEH-tra], which refers to a large rock or bedrock. It is feminine and differs slightly in connotation from Κηφᾶς, which is specifically a name given to a person.
