Thomas (= Didymus = twin);
Known as "Unbeliever Thomas" because without having seen Jesus, he did not believe in his resurrection. His mission ended in India where he was executed for his belief in Mailapur (Indian Christians are called Thomas Christians).

"Apostle":
To the concept of the Christian. Apostles (Greek apostolos = messenger, messenger) belong to the authority and mission of God or Christ. That is why the church sees itself as apostolic. As God's messenger, the apostle demands that his word be heard as God's word.

The epoch of early Christianity is often referred to as the Apostolic Age, in which some of the 12 apostles still lived and led various congregations.

This age ends with the destruction of Jerusalem by the Romans in 70, which ended the Jewish uprising (c. 66-70).

Apostle Paul:
An important apostle in the following of Jesus was Paul, who was committed to the apostolic mandate after an apparition of the risen Christ and the mission through him. Paul began each of his letters with the words: "Paul, by the will of God called apostle of Christ (...)"

The post-apostolic time:

Most of the time early Christianity is also understood to mean the time when none of the 12 apostles lived, John died about 100, but a larger number of Christians had known them.

The time limit for this can be drawn around 150, the epoch of the first church fathers.
