The Greek that is transliterated “Cephas” in English — and is an alternative name for Peter — is transliterated in Chinese Protestant translations as jīfǎ (traditional Chinese: 磯法, simplified Chinese: 矶法). The first character (磯 / 矶) is not only chosen because of its sound but also because of its meaning: “rock,” corresponding to the meaning of the Aramaic kēp̄ā (כֵּיפָא) to which the Greek Kēphâs (Κηφᾶς) refers and also alluding to Jesus’ proclamation in Matthew 16:18 (see Peter – rock).

Note that Catholic Chinese versions don’t follow the English pronunciation of “Cephas” with its opening [s] sound. They use kēfǎ (刻法) transliterating the [k] sound from the Aramaic and Greek. Kēfǎ does not carry the additional meaning of “rock.” (Source: Jost Zetzsche)

In the Neo-Aramaic language of Assyrian the terms used for both “Peter” (English transliteration of the Greek “πετρος”) and “Cephas” are identical (كِيپَا, pronounced kēpā). (Source: Ken Bunge)
