Our FSSP Priest explained a couple of symbols to us about the Traditional Mass.
The extending and re-joining of the hands over the altar is to siignify the sacrifice taking place. I guess it is a refined gesture of aJewish sacrificial ritual, but I am not exactly sure. Anyway, each time I see him make the gesture I am reminded with my eyes what the Church teaches about the Mass.
The changing of the Missal from the Epistle side to the Gospel side is to remind us of the revelation of the Word of God being taken from the Jews and given to the Gentiles. Again, a visual reminder of what the Church teaches.
Fr said it was the great wisdom of the Church that sees fit to engage all 5 senses we have to reinforce spiritual realities that are ordinarily imperceivable to the senses, such as incense, candles, liturgy and ritual, vestments, architecture etc.
He is right, and snice he explained just a few of the symbols of Mass, I have not forgotten them. When my children ask me one day why does he do this and that, I will have another opportunity to teach them the faith, which might not have come my way if the Church, like Protestants, despised and discouraged external signs, because they were not necessary. If only Protestants knew how much depth of the faith their ancestors threw out when they started their own religion!
Long live the Traditional Mass.
