According to Catholic teachings, what was the First Temptation of Christ basically about?

We read in Mtt 4:1-4, of the Temptation of Jesus in the wilderness : > Then Jesus was led up by the Spirit into the wilderness to be tempted by the devil. He fasted forty days and forty nights, and afterwards he was famished. The tempter came and said to him, “If you are the Son of God, command these stones to become loaves of bread.” Here, we see the Devil using calculated words, i.e. "IF you are the Son of God......"In other words, the Devil was asking Jesus to disclose his divinity, as if he was not sure of whom he was tempting. Elsewhere, we see Jesus forbidding his own disciples from telling others that he is the Messiah ( Mtt 16:20; Mk 8:30). That said, the Devil was presumably tempting Jesus to disclose his divinity much before the appointed time. But, the motifs of the First Temptation we have, are of stone and bread . My question therefore, is: According to Catholic teachings, what was the First Temptation of Christ basically about ?
