Or perhaps what St. Siricius declared:
On the first page of your letter, therefore, you indicated that multitudes who were baptized by the impious Arians were hastening to the catholic faith, and that certain of our brothers wished to baptize these same people again. This is not allowed, since both the Apostle forbids and the canons oppose doing it; and after the Council of Rimini was annulled, the general decrees sent to the provinces by my predecessor of venerable memory Liberius prohibit it. We unite these people, and the Novatianists and other heretics, to the assembly of Catholics, just as it was constituted in the synod, solely through invocation of the sevenfold Spirit by imposition of the bishop's hand. Indeed all the East and the West preserves this practice, and it is also inappropriate henceforth for you to deviate from that path, if you do not wish to be separated from our company by synodal sentence. (Letter to Himerius of Tarragona, 385 AD)
As Supreme Pontiff of the Catholic Church, he, unlike the pseudonymous author of the "Apostolic Canons", actually had authority to decree men excommuicate.
Re "As Supreme Pontiff of the Catholic Church, [St. Siriacus] unlike the pseudonymous author of the 'Apostolic Canons', actually had authority to decree men excommunicate", and your two long posts.
Nothing you say changes anything. Roman Catholic teaching is at odds with the the teaching of the Orthodox Church. So what else is new? Move on.
