In Acts 1:24-26 it is used to determine which man God willed to take Judas’ place
And they prayed and said, “You, Lord, who know the hearts of all, show which one of these two you have chosen to take the place in this ministry and apostleship from which Judas turned aside to go to his own place.” And they cast lots for them, and the lot fell on Matthias, and he was numbered with the eleven apostles.
That goes beyond flipping a coin and leaving God out of the equation. It is trying to determine the will of God through it. I am ex-pagan and many of my divination rites consisted of me asking yes/no questions through essentially a method similar to casting lots.
Further more the Catechism specifically forbids it
2116 All forms of divination are to be rejected: recourse to Satan or demons, conjuring up the dead or other practices falsely supposed to “unveil” the future. Consulting horoscopes, astrology, palm reading, interpretation of omens and lots, the phenomena of clairvoyance, and recourse to mediums all conceal a desire for power over time, history, and, in the last analysis, other human beings, as well as a wish to conciliate hidden powers. They contradict the honor, respect, and loving fear that we owe to God alone.
And St. Aquinas’ similarly condemns it in the Summa Theologica
It is written in the Decretals (XXVI, qu. v, can. Sortes): “We decree that the casting of lots, by which means you make up your mind in all your undertakings, and which the Fathers have condemned, is nothing but divination and witchcraft. For which reason we wish them to be condemned altogether, and henceforth not to be mentioned among Christians, and we forbid the practice thereof under pain of anathema.”
However St. Aquinas concedes later on in the article
If, however, there be urgent necessity it is lawful to seek the divine judgment by casting lots, provided due reverence be observed.
There is a problem with this logic:
St. Aquinas’ held there to be 3 types of commandments from the Law:
Divination would fall under the First Commandment (which is what it is sectioned under in the Catechism) and thus would be a moral law.
Yet, God’s moral law never changes.
How could God allow a moral commandment that never changes to be practiced not just under the “necessity” of electing Matthias, but just in general in the rest of the Bible? God is giving His will through stones? How can this possibly not be some form of Judaized idolatry?
It’s really upset my faith and all answers I’ve got so far have only frustrated me further. I’m upset enough to the point where I am considering just leaving the faith. It seems like such a blatant contradiction that the CCC and St. Aquinas and early Church would condemn it as witch craft… the Apostles were literally committing witch craft? What? How do I even justify that?
