The field was abundant with the fruits of virtue, compared to the rewards of our good deeds, which may be harmed by storms, or diminished by drought, or laid into the blessed storehouses by the harvesters. Thus, the earth had embraced the Word of God, and the good field, sown with divine seed, had yielded bountiful spiritual harvest. The disciples were fervent in their desire for the salvation of souls, and through their wondrous deeds, they seemed to extract the fruits of faith from the shells of the human body. Although the Jews believed this was prohibited on the Sabbath (see Luke 6:2), Christ demonstrated the futility of the law and the power of grace by imparting new grace.
I believe the references to the Sabbath in both Matthew and Mark hold sacramental significance, as the Sabbath symbolizes the eternal rest of resurrection. In this present age, with the Jewish customs rendered obsolete, and in the age to come, when we will partake in eternal joy, we will enjoy the blessings of the earth, as it is written, “There is, and ye shall eat” (Isaiah 65:13). Notably, St. Luke refers to the second-first Sabbath rather than the first-second, indicating its precedence due to its superiority. This is the second Sabbath, as the first was established by the law, which even imposed penalties on those who labored on that day (see Exodus 31:14); however, it is also the first because the original Sabbath under the law has been abolished, making this one, established by the new, the first in grace. It is now permissible to work on the Sabbath without fear of punishment! Of the Sabbath under the law, which has lost its authority, not even a name remains, even though it initially preceded this new Sabbath, which is first in the blessings it offers. The two Adams reflect this distinction: the first Adam was a living soul, but the last Adam became a life-giving spirit (1 Cor. 15:45), and the first man was made from the earth, while the second Man is from heaven (1 Cor. 15:47). Therefore, the second Adam surpasses the first: the first brought death, while the second brings life (cf. Rom. 5:14; Jn. 10:10, 28). Thus, the designation of the Sabbath as second-first reflects its order in time and primacy in grace. A Sabbath that allows for forgiveness is far superior to one that imposes penalties. The law was first, followed by the gospel, but grace eclipses fear. The Gospel is primary because it is part of God's divine plan, although it follows in its realization.
