Zacchaeus (Greek: Ζακχαῖος, Zakchaios; Hebrew: זכי, "pure", "innocent") was a chief tax-collector at Jericho, mentioned only in the Gospel of Luke. A descendant of Abraham, he was an example of Jesus' personal, earthly mission to bring salvation to the lost. Tax collectors were despised as traitors (working for the Roman Empire, not for their Jewish community), and as being corrupt. Because the lucrative production and export of balsam was centered in Jericho, his position would have carried both importance and wealth. In the account, he arrived before the crowd who were later to meet with Jesus, who was passing through Jericho on his way to Jerusalem. Described as a short man, Zacchaeus climbed up a sycamore fig tree so that he might be able to see Jesus. When Jesus reached the spot he looked up into the branches, addressed Zacchaeus by name, and told him to come down, for he intended to visit his house. The crowd was shocked that Jesus, a religious teacher/prophet, would sully himself by being a guest of a tax collector.
At Er-riha (Jericho) there is a large, venerable looking square tower, which by tradition is named the House of Zacchaeus.
Clement of Alexandria refers once to Zacchaeus in a way which could be read as suggesting that some identified him with Matthias, who took the place of Judas Iscariot after Jesus' ascension. Luke told us that Matthias in the beginning was with Jesus since the baptism of John (Acts 1:21-23). John also told us that later many of his disciples turned back and no longer followed him (John 6:60-66). The later Apostolic Constitutions identify "Zacchaeus the Publican" as the first bishop of Caesarea (7.46).
Medieval legend identified Zacchaeus with Saint Amadour, and held him to be the founder of the French sanctuary, Rocamadour.
In Eastern Orthodox and Greek-Catholic Churches of Slavic tradition, the Gospel account of Zacchaeus is read on the last Sunday preceding the liturgical preparation for Great Lent, for which reason that Sunday is known as "Zacchaeus Sunday." It is the very first commemoration of a new Paschal cycle. The account was chosen to open the Lenten season because of two exegetical aspects: Jesus' call to Zacchaeus to come down from the tree (symbolizing the divine call to humility), and Zacchaeus' subsequent repentance.
In the Eastern churches of Greek/Byzantine tradition, Zacchaeus Sunday may fall earlier than the Sunday before the Pre-Lenten season.
In Western Christianity, the gospel pericope concerning Zacchaeus is the reading for a Dedication of a Church or its anniversary. On Dedication, red-white banners (instead of the usual yellow-white ones) are flown from the Church tower, which are consequently called the Zacchaeus flag.
The story of Zacchaeus is used by some to illustrate the saying of Jesus: "Blessed are the pure of heart, for they shall see God" Matthew 5:8, because the name Zacchaeus means 'pure'. Zacchaeus also becomes a contrast of character with the Rich Young Ruler Luke 18:18-23. Both Zacchaeus and the Rich Young Ruler were wealthy men, but one was self-righteous and would not give up his possessions, while the other gave half his possessions to feed the poor.
