God also said to Abraham:
“On your part, you and your descendants after you must keep my covenant throughout the ages. This is my covenant with you and your descendants after you that you must keep: every male among you shall be circumcised.
Before God gave the Law to Moses on Mount Sinai, he gave the circumcision to Abraham; keeping the law and circumcision are signs of the covenant. Readers of the lectionary today might notice Genesis 17 has been redacted heavily, and several verses concerning circumcision are not included in today's text. I'm sure the editors have their reason but they offer no explanation. Perhaps January 1 is no longer "the Feast of the circumcision of Jesus" for the same reason. It just seems like not a nice thing to talk about.
But Christians would do well to consider the gifts that come with God's covenant. Circumcision is a physical sign of God's claim on Abraham and his descendants. In that respect it resembles Baptism and Eucharist. By these sacraments we are incorporated into the Lord and become physically kin to Jesus as Jews are physically kin to the LORD by circumcision.
This physical relation sustains our belonging to the Lord; it anchors our spirituality in our physical bodies, in corporate institutions, and in human history. One does not simply say, "I belong to God" or "I belong to Christ" without either of those signs.
A modern reader might ask, "What about women? They are not circumcised, and there is no mention of female circumcision in the Bible. Despite the deletions, today's reading includes Sarah by her marriage to Abraham. As wife of Abraham and mother of Isaac, her marriage is no less physical than circumcision. Christian women belong to Jesus in the same sacramental way.
As issues of sexuality and marriage have become highly controversial today, Catholics return to the Bible and the Magisterium of the Church for guidance. There we discover that our covenant with God is more than detente, agreement, or treaty. It is not dissolved by one-sided or two-sided consent. There is no divorce in a covenant; not with God, nor among men and women. The Lord is our God forever, and we are his people forever; from one generation to the next.
The persistence of antisemitism reminds us of this everlasting covenant. So long as Satan makes war against God, the persecution of his people continues. Those who hate Jews hate God, and their hatred is all inclusive; it knows no bounds. No one should be surprised when synagogues and churches are vandalized.. They are the world's response to Abraham's God. Nor is the individual Jew or Christian given a free pass if they renounce their religious heritage. In times of persecution they are rounded up like the rest.
As the Catholic Church engages in a three year preparation for the Eucharistic Congress in Indianapolis next year, we ponder the privilege, responsibility, and burden of belonging physically to the Lord. We thank God for the gift, and pray daily that we might be found worthy to belong in this company of saints and martyrs.
