I am sorry I didn't write on the forum for few days.
So, the way I see and the way many people see it, Leo I was the first Pope to explicitly teach Papal Primacy...
Here, he calls himself not only head of the church but calls himself a master, while calling Dioscurus - a disciple.
Take a closer look:
For since the most blessed Peter received the headship
of the Apostles from the Lord, and the church of Rome still abides by His institutions, it is wicked to believe that His holy disciple Mark
, who was the first to govern the church of Alexandria, formed his decrees on a different line of tradition: seeing that without doubt both disciple and master drew but one Spirit from the same fount of grace
, and the ordained could not hand on aught else than what he had received from his ordainer
. We do not therefore allow it that we should differ in anything, since we confess ourselves to be of one body and faith, nor that the institutions of the teacher should seem different to those of the taught
At first you think the words "teacher", "master" and "ordainer" refers to Christ, but it's actually Peter, who now is Pope of Rome.
At first the phrase: "both disciple and master drew but one Spirit from the same fount of grace[/b], and the ordained could not hand on aught else than what he had received from his ordainer
. We do not therefore allow it that we should differ in anything"
The fount of grace here is Christ. Also, the words "ordained" and "ordainer" are both singular, thus the phrase - "we should not differ", in this phrase "we" is among "ordainer and ordained" and not between two ordained...
Also, Christ had no church tradition, Christ established the Church. Thus it's about Peter who established the tradition, about which Leo says is a Master.
I read it this way...
