I guess I am wondering about the Markan mistake that Jesus was crucified at the third hour. It was the sixth hour as even the Marcosians knew. So what originally happened at the third hour? Ignatians to the Trallians 9:
On the day of the preparation, then, at the third hour, He received the sentence from Pilate, the Father permitting that to happen; at the sixth hour He was crucified; at the ninth hour He gave up the ghost; and before sunset He was buried.
The Nag Hammadi text Melchizedek:
And you crucified me from the third hour of the Sabbath-eve until the ninth hour.
The Gospel of Peter:
And it was the third hour, and they crucified him.
On the hours of prayer in Tertullian On Fasting:
In like manner they censure on the count of novelty our Stations as being enjoined; some, moreover, (censure them) too as being prolonged habitually too late, saying that this duty also ought to be observed of free choice, and not continued beyond the ninth hour,-- (deriving their rule), of course, from their own practice. Well: as to that which pertains to the question of injunction, I will once for all give a reply to suit all causes. Now, (turning) to the point which is proper to this particular cause--concerning the limit of time, I mean--I must first demand from themselves whence they derive this prescriptive law for concluding Stations at the ninth hour. If it is from the fact that we read that Peter and he who was with him entered the temple "at the ninth (hour), the hour of prayer," who will prove to me that they had that day been performing a Station, so as to interpret the ninth hour as the hour for the conclusion and discharge of the Station? Nay, but you would more easily find that Peter at the sixth hour had, for the sake of taking food, gone up first on the roof to pray; so that the sixth hour of the day may the rather be made the limit to this duty, which (in Peter's case) was apparently to finish that duty, after prayer. Further: since in the self-same commentary of Luke the third hour is demonstrated as an hour of prayer, about which hour it was that they who had received the initiatory gift of the Holy Spirit were held for drunkards; and the sixth, at which Peter went up on the roof; and the ninth, at which they entered the temple: why should we not understand that, with absolutely perfect indifference, we must pray always, and everywhere, and at every time; yet still that these three hours, as being more marked in things human-- (hours) which divide the day, which distinguish businesses, which re-echo in the public ear--have likewise ever been of special solemnity in divine prayers? A persuasion which is sanctioned also by the corroboratire fact of Daniel praying thrice in the day; of course, through exception of certain stated hours, no other, moreover, than the more marked and subsequently apostolic (hours)--the third, the sixth, the ninth. And hence, accordingly, I shall affirm that Peter too had been led rather by ancient usage to the observance of the ninth hour, praying at the third specific interval, (the interval) of final prayer.
These (arguments), moreover; (we have advanced) for their sakes who think that they are acting in conformity with Peter's model, (a model) of which they are ignorant: not as if we slighted the ninth hour, (an hour) which, on the fourth and sixth days of the week, we most highly honour; but because, of those things which are, observed on the ground of tradition, we are bound to adduce so much the more worthy reason, that they lack the authority of Scripture, until by some signal celestial gift they be either confirmed or else corrected. "And if," says (the apostle), "there are matters which ye are ignorant about, the Lord will reveal to you." Accordingly, setting out of the question the confirmer of all such things, the Paraclete, the guide of universal truth, inquire whether there be not a worthier reason adduced among its for the observing of the ninth hour; so that this reason (of ours) must be attributed even to Peter if he observed a Station at the time in question. For (the practice) comes from the death of the Lord; which death albeit it behoves to be commemorated always, without difference of hours yet are we at that time more impressively commended to its commemoration, according to the actual (meaning of the) name of Station. For even soldiers, though never unmindful of their military oath, yet pay a greater deference to Stations. And so the "pressure" must be maintained up to that hour in which the orb--involved from the sixth hour in a general darkness--performed for its dead Lord a sorrowful act of duty; so that we too may then return to enjoyment when the universe regained its sunshine. If this savours more of the spirit of Christian religion, while it celebrates more the glory of Christ, I am equally able, from the self-same order of events, to fix the condition of late protraction of the Station; (namely), that we are to fast till a late hour, awaiting the time of the Lord's sepulture, when Joseph took down and entombed the body which he had requested. Thence (it follows) that it is even irreligious for the flesh of the servants to take refreshment before their Lord did.
