This general audience by Pope Francis is worth reading. It seems to be another implicit commentary on his critics.
“Dear brothers and sisters, this first exposition of the Apostle to the Galatians presents the radical newness of the Christian life: all those who have faith in Jesus Christ are called to live in the Holy Spirit, who liberates from the Law and, at the same time, brings it to fulfillment according to the commandment of love. This is very important. The Law leads us to Jesus. But one of you might say to me: “But, Father, just one thing: does this mean that if I pray the Creed, I do not need to observe the commandments?” No, the commandments are valid in the sense that they are “pedagogues” [teachers] that lead you toward the encounter with Christ. But if you set aside the encounter with Jesus and want to go back to giving greater importance to the commandments, this was the problem of these fundamentalist missionaries who had infiltrated the Galatians to confuse them.”
Those who infiltrate the Church and the Gospel are not the Popes and Bishops, but rather those who are rebelling against Church leaders. Pope Francis is like Saint Paul, and those who infiltrated to confuse the Galatians and lead them astray are like the critics of Pope Francis and the opponents of TC.
