From the earliest days of the Church, Christians venerated martyrs on the anniversary of their deaths by celebrating Mass on their tombs. Over the next few centuries relics began to be transferred between dioceses and memorials for several martyrs were celebrated in common. During the persecutions of Diocletian in the early 300s so many Christians were killed that it became impossible to create separate memorials for each so joint memorials became common.
In the late 300s St. Basil the Great sent a letter to the bishops of Pontus inviting them to celebrate a common feast in honor of the martyrs.
The earliest record of a feast honoring all Christian martyrs is from a homily of St. John Crysostom in the 407 saying that there was a feast celebrated in Constantinople.
"All who die in God's grace and friendship, but still imperfectly purified, are indeed assured of their eternal salvation; but after death they undergo purification, so as to achieve the holiness necessary to enter the joy of heaven.
The Church gives the name Purgatory to this final purification of the elect, which is entirely different from the punishment of the damned. The Church formulated her doctrine of faith on Purgatory especially at the Councils of Florence and Trent. The tradition of the Church, by reference to certain texts of Sacred Scripture, speaks of a cleansing fire:
As for certain lesser faults, we must believe that, before the Final Judgment, there is a purifying fire. He who is truth says that whoever utters blasphemy against the Holy Spirit will be pardoned neither in this age nor in any age to come. From this sentence we understand that certain offences can be forgiven in this age, but certain others in the age to come.
This teaching is also based on the practice of prayer for the dead, already mentioned in Sacred Scripture: 'Therefore [Judas Maccabeus] made atonement for the dead, that they might be delivered from their sin. From the beginning the Church has honored the memory of the dead and offered prayers in suffrage for them, above all the Eucharistic sacrifice, so that, thus purified, they may attain the beatific vision of God."
