There is no rotation of Scriptures at a Tridentine Mass.
You will hear the same epistle and Gospel for the Third Sunday of Easter that you heard last year, and the year before that, and that you will hear next year.
There are many Tridentine Mass advocates who seem willing to admit that the cycle of A, B, and C readings, and the addition of a third reading, is an improvement, and they would even be willing to consider the adaptation of more Scripture.
But, they seem to be few in number.
