The New Testament clearly describes how Jesus appointed 12 “apostles” in his lifetime to preach the good news to all creation.
Yet, the Catholic Church often uses the word “apostle” in reference to other saints as well, raising the question, “How many apostles are there?”
The English word “apostle” is derived from the Greek apostello, “to send forth.” An apostle is one who is “sent” by God to preach the Gospel to the nations. This is typically used in reference to the original 12 apostles who were sent into the world by Jesus.
However, the New Testament names several other disciples of Christ as “apostles.”
