One notable thing about the text is its focus on outward practice, rather than belief, which is consonant with (pre-Christian) Roman religion. No item speaks of a required belief or creed, except as subordinate to the concerns about the practice of rebaptism, and there only requiring one "to have been baptized into the Father and the Son and the Holy Spirit" or to receive baptism with such a formula. There is no attempt to work out the theological meaning of the Father, the Son, and the Holy Spirit, only a requirement that a baptismal creed formula have the three. This addresses a concern of the schism regarding rebaptism, practiced by the "Africans."
In this regard, it is similar to the first 21 canons attributed to the Council of Elvira: https://web.archive.org/web/20120716202 ... Canons.htm
The concerns of the schism with betrayers/traitors is taken up under "Concerning those who are said to have handed over the Holy Scriptures or sacred vessels or the names of their brothers..." Given the proximity in time to the persecution itself, this shows that some had handed over scriptures, along with other items being confiscated, such as things made of valuable silver and gold.

(xv) Letter of the Council of Arles [314]
Being united by the common tie of charity, and by that unity which is the bond of our mother, the Catholic Church, we have been brought to the City of Arles by the wish of the most pious Emperor, and we salute thee with the reverence which is thy due, most glorious Pope. Here we have suffered from, troublesome men, dangerous to our law and tradition----men of undisciplined mind, whom both the authority of our God, which is with us, and our tradition and the rule of truth reject, because they neither have reasonableness in their argument, nor any moderation in their accusations, nor was their manner of proof to the point. Therefore by the Judgement of God and of Mother Church, who knows and approves her own, they have been either condemned or rejected. And would, most beloved Brother, that you had deemed it well to be present at this great spectacle. We believe surely that in that case a more severe sentence would have been passed against them; and our assembly would have exulted with a greater joy, had you passed Judgement together with us. But since you were by no means able to leave that region, where the Apostles daily sit, and their blood without ceasing bears witness to the glory of God, it did not seem to us that by reason of your absence, most well-beloved Brother, we ought to deal exclusively with those matters, on account of which we had been summoned, but we judged that we also should take counsel on our own affairs; because, as the countries from which we come are different, so events of various kinds will happen which we think that we ought to watch and regulate. Accordingly we thought well in the presence of the Holy Spirit and His Angels that from among the various matters which occurred to each of us, we should make some decrees to provide for the present state of tranquillity. We also agreed to write first to you, who hold [the government of] the greater dioceses, that by you especially they should be brought to the knowledge of all. What it is that we have determined on, we have appended to this writing of our insignificance.
[1] But in the first place, we were bound to discuss a matter that concerned the usefulness of our life. Now since one died and rose again for many, the same season should be observed with a religious mind by all at the same time, lest divisions or dissensions might arise in so great a service of devotion. We judge, therefore, that the Pasch of the Lord should be observed throughout the world upon the same day.
[2] Also, concerning those who have been ordained clerics in any places whatsoever, we have decreed that they remain fixed in the same places.
[3] Concerning those too who throw down their arms in time of peace, we have decreed that they should be kept from communion.
[4] Concerning the wandering agitators who belong to the Faithful, we have decreed that, as long as they continue their agitation, they be debarred from communion.
[5] Concerning the strolling players we have decreed that, as long as they act, they be debarred from communion.
[6] Concerning those [heretics] who are weighed down by illness and wish to believe, we have decreed that hands be laid upon them.
[7] Concerning magistrates who belong to the Faithful and are appointed to office, we have determined that, when they are promoted, they should receive ecclesiastical letters of communion, but in such a way that in whatever place they may be living, the Bishop of that place shall have a heed to them, and if they begin to act against discipline, they be then excluded from communion.
[8] We have decreed similarly with regard to those who wish to hold state offices.
[9] Moreover, with regard to the Africans, inasmuch as they use their own law of rebaptising, we have decreed that if any heretic comes to the Church, he should be questioned concerning the Creed, and if it be found that he has been baptised in the Father and the Son and the Holy Ghost, hands shall be laid upon him and no more. But if, on being questioned as to the Creed, he does not give the Trinity in answer, then let him rightly be baptised, and the rest, etc.

That which we in common council have decreed, we hereby make known to your most esteemed person, so that also <all> the bishops might know what ought to be observed in the future.
1. In the first place, concerning the celebration of Easter Sunday: That it be observed by us on one day and at one time in all the earth, and that you should send out letters to all, as is the custom.
2. Concerning those who have been ordained ministers in certain places: They are to continue to serve in those same places.
3. Concerning those who lay down their weapons in peacetime, be it resolved that they be excluded from fellowship.
4. Concerning charioteers who are among the faithful, be it resolved that as long as they continue to drive in chariot races they be excluded from fellowship.
5. Concerning actors, be it further resolved that as long as they continue to carry on that occupation they be excluded from fellowship.
6. Concerning those who in time of sickness wish to confess the faith, be it resolved that they ought to receive the laying on of hands.
7. Concerning officials who are among the faithful who serve in the government, be it is resolved thus, that when they are transferred, they should receive letters of reference from their churches, so that, therefore, in whatever places they serve, they can be cared for by the bishop of that place, and when they begin to act against the church’s discipline, that only then they be excluded from fellowship.
8. Similarly also concerning those who wish to pursue a public career.
9 (8). Concerning the Africans who use their own special law in that they practice rebaptism, it is resolved that if any come to the church from heresy, they question him on the creed (used at his baptism), and if they consider him to have been baptized into the Father and the Son and the Holy Spirit, let him only receive the laying on of hands so that he receive the Holy Spirit; but if when questioned he does not solemnly confess this Trinity, let him be baptized.
10 (9). Concerning those who carry letters from the confessors, be it resolved that, when they have handed over those letters, they receive other letters of reference.
11 (10). Concerning those who apprehend their wives in adultery, and the same persons are faithful youths and are prevented from marrying (again), be it resolved that, as much as is able, they be counseled not to take other wives while their own wives are still living, even if the latter are adulterous.
12 (11). Concerning young women among the faithful who are getting married to unbelievers, be it resolved that they be excluded from fellowship for a considerable period of time.
13 (12). Concerning clergy who lend money at interest, be it resolved that, in accordance with the divinely given model, they be excluded from fellowship.
14 (13). Concerning those who are said to have handed over the Holy Scriptures or sacred vessels or the names of their brothers, be it resolved by us that any of those who from the public records, not from words alone, are discovered to have done so be removed from the office of the clergy. But if that same person who was exposed has ordained others, and the affairs of those ordained are all in order, let their ordination not be revoked. And whereas there were many who seemed to fight against the church and who thought they could disprove the accusations made against them by the testimony of paid witnesses they should not be cast out altogether, but only, as stated above, if their guilt is shown by public records.
15 (14). Concerning those who have falsely accused their brothers, be it resolved that they not be given fellowship as long as they live.
16 (15). Concerning deacons who we have learned are conducting services in many places, be it resolved that this ought to happen as little as possible.
17 (16). Concerning those who have been excluded from fellowship because of their own wrongdoing, be it resolved thus, that in whatever place they have been excluded, they must be re-admitted to fellowship in that same place, so that no bishop oversteps another bishop.
18. Concerning the deacons of a city: That they not presume too much for themselves, but reserve honor for the presbyters, so that they do nothing of importance without the presbyter’s knowledge.
19. Concerning foreign bishops who are accustomed to come into a city, be it resolved that they be given a place where they can conduct services.
20. Concerning those who assume that they have the right individually by themselves to ordain a bishop, be it resolved that no one presume to do this by himself; but only if there are an additional seven bishops with him; if, however, it is not possible <to have seven present>, they dare not ordain someone with less than three bishops present.
21. Concerning presbyters and deacons who were accustomed to leave the place where they were ordained and have gone to different <places>, be it resolved that they serve in those places; but if, they leave these places and wish to transfer themselves to yet another locale, they should be deposed.
22. Concerning those who apostasize and never present themselves again to the church, neither seeking to do acts of repentance nor even afterwards; if then they are seized by sickness and seek to be received into fellowship, be it resolved that they not be given fellowship, unless they recover their strength and bring forth fruits worthy of repentance.
