How did the church discipline members, and could the excommunicated return?
What the sources show
Didachec. 100 · Tertullianc. 197Cut off
From the Didache on, the church corrected members and cut off from prayer and fellowship those who would not repent. Tertullian calls it a foretaste of the last judgment. 12
Cyprian of Carthagec. 252 · Gregory of Nyssac. 390 · Ambrose and Theodosius (as Sozomen reports)c. 390
The aim was return: after penance, sometimes long and in stages, the excommunicated were readmitted, and no dying penitent was refused. Even an emperor, Theodosius, was barred by Ambrose until he did penance. 356

Correct one another, not in anger but in peace, as you have it in the Gospel. And let no one speak to anyone who has wronged another, nor let him hear from you, until he repents.
Matthew 18 put into practice: shunning until repentance.

There too are exhortations, rebukes and divine censure. For judgment is passed with great weight, as among people sure that they are in God's sight, and it is the gravest foretaste of the judgment to come if anyone has sinned so that he is cut off from sharing in prayer, in the assembly, and in all holy fellowship.
The earliest description of excommunication as a practice.

Cyprian of Carthage c. 200–258 ADLetter 57 57.1
Those who had fallen ... should do full penance for a long time, and if danger of sickness pressed, should receive peace at the point of death. For it was not right, nor did fatherly love and divine mercy allow, that the Church should be shut to those who knock.
"Peace" means readmission to communion.

Gregory Thaumaturgus c. 213–c. 270 ADCanonical Letter Canon 11
The weeping is outside the gate of the house of prayer, where the sinner must stand and beg the faithful who enter to pray for him. The hearing is within the gate in the narthex, where the one who has sinned must stand as far as the catechumens, and then go out; for hearing the Scriptures and the teaching, as it says, let him be cast out and not be counted worthy of prayer. The kneeling is that he stand within the gate of the temple and go out with the catechumens. The standing with is that he stand with the faithful and not go out with the catechumens. Last, the partaking of the holy things.
The grades of penance, ending in restored communion: weeping, hearing, kneeling, standing with, and at last partaking. The locked library section covers only Canon 1 of this letter, so Canon 11 is read from the Documenta Catholica Omnia copy text kept in the book's sources; its spellings (χρἠ, μετᾶ) are kept from that copy text.
Ambrose and Theodosius (as Sozomen reports)Sozomen, Church History 7.25.1–2
When the emperor came to the church to pray, Ambrose, the bishop of the city, met him at the doors, took hold of his purple robe before the crowd, and said: "Stop! A man defiled by sin, with hands stained with blood unjustly, may not cross the threshold of the sanctuary before repentance, or share in the divine mysteries." The emperor, amazed at the priest's boldness, turned back thoughtful, stung with repentance.
After the massacre at Thessalonica (390). Theodosius did public penance and was readmitted. Ambrose's own letter (Letter 51) is more private in tone.
Gregory of Nyssa c. 335–c. 395 ADCanonical Letter to Letoius canon 4
... the choice of the penitent being tested in this too, so that if his turning is trustworthy, the number of years need not be kept in every case, but he may be brought quickly to restoration in the Church and to sharing in the good.
Penance came in years and grades (weepers, hearers, kneelers, standers), but a bishop could shorten them.
