Apostle of the Germans in the context of "Catholic Church in Germany"

An apostle (/əˈpɒsəl/), in its literal sense, is an emissary. The word is derived from Ancient Greek ἀπόστολος (apóstolos), literally "one who is sent off", itself derived from the verb ἀποστέλλειν (apostéllein), "to send off". The purpose of such sending off is usually to convey a message, and thus "messenger" is a common alternative translation; other common translations include "ambassador" and "envoy". The term in Ancient Greek also has other related meanings.

In Christianity, the term was used in the New Testament for Jesus' Twelve Apostles (including Peter, James, and John), as well as a wider group of early Christian figures, including Paul, Barnabas, and Junia. The term is also used to designate an important missionary of Christianity to a region or a group, e.g. Patrick, the apostle of Ireland, or Boniface, the "apostle of the Germans". Some other religions use the term for comparable figures in their history. The word in this sense may be used metaphorically in various contexts, but is mostly found used specifically for early associates of the founder of a religion, who were important in spreading their teachings. The term is also used to refer to someone who is a strong supporter of something.
