Here are the 25 Apostles mentioned in the New Testament--note again that Christ had sent out 70--all apostles, just not part of the 12, who represented the 12 tribes of Israel.
How Many Apostles?
Let’s start counting. Yes, there were the twelve chosen by Jesus. Eleven are named in Acts 1:13, “Peter and John, and James and Andrew, Philip and Thomas, Bartholomew and Matthew, James the son of Alphaeus and Simon the Zealot, and Judas the son of James. “ Judas Iscariot, one of the original twelve, the one who betrayed Jesus, is not named in that list. That’s the original twelve. Then add Matthias who replaced Judas Iscariot to become one of the twelve apostles of the Lamb (Acts 1:26). “And the wall of the city had twelve foundations, and in them the names of the twelve apostles of the Lamb” (Revelation 21:14). When we include both Judas and Matthias the total is now thirteen.
We know additional apostles besides these men exist because Christ, after His ascension, appointed “some as apostles, some as prophets, some as evangelists, and some as pastors and teachers . . .
until we all attain to the unity of the faith and of the knowledge of the Son of God, to a mature man, to the measure of the stature which belongs to the fullness of Christ” (Ephesians 4:11-13). Are we there yet? Have we all attained to the unity of the faith? Or mature manhood? Or the fullness of Christ? Clearly, the apostolic ministry will continue until Christ returns!
An investigation of the Scripture reveals several individuals in addition to the original twelve who are explicitly referred to as apostles. We might call them “apostles of the throne“, “apostles of the Lamb” or “ascension-gift apostles.” A complete listing of New Testament apostles follows.
James, the half brother of Jesus and leader of the Jerusalem church—Galatians 1:19
Barnabas–Acts 14:14
Paul–Acts 14:14 and many other references
Apollos– Corinthians 4:6-9
Timothy and Silvanus– I Thessalonians 1:1 and 2:6
Epaphroditus–Philippians 2:25. While the King James Version translates the word as “messenger”, the Greek word (apostolon) is actually “apostle”.
Two unnamed apostles–Second Corinthians 8:23. A brother of fame among the churches, and a brother tested–“As for our brethren, they are messengers of the churches, a glory to Christ.” Again, the Greek word is “apostoloi” but is translated here as “messengers”.
These nine now make a total of 22 (13 + 9 = 22).
Andronicus and Junia–Romans 16:7 “Salute Andronicus and Junia, my kinsmen, and my fellow prisoners, who are of note among the apostles, who also were in Christ before me.” If we count Andronicus and Junia, the total jumps to 24.
How Many Apostles?
Finally, Hebrews 3:1 designates Jesus Christ the “Apostle and High Priest of our profession.”
That makes 25 apostles in the New Testament!
