The Gospel for Saturday, March 5, 2022, in the Ancient Rite (TLM) was the account from Mark of Jesus walking on the water (Mark 6:47-56). The same story appears in Matt 14.22-33 and John 6.16-21.
As usual, there are differences in the Gospel accounts, and some "anti-primacy of Peter types" like to stress that Mark and John do not mention Peter walking on the water to Jesus, as does Matthew.
However, as is well-known, John's Gospel is not considered one of the "synoptics" because John had an entirely different aim in writing his gospel. So no surprise that John's Gospel leaves out details that the synoptics do not.
And as for Mark, it is well-known that Mark was Peter's "secretary" and it can be easily understood that Peter, in dictating to Mark, did not want to highlight himself in any way.
