Here's answer to week's question
(From page 2)
A revelation received by Joseph Smith in January 1832 clarifies the passage, which was given by the Apostle Paul to resolve contention regarding the matter of circumcision. Under the gospel of Jesus Christ, the law of circumcision is no longer in effect; little children already are sanctified through the atonement of Jesus Christ and do not need circumcision to make them holy. Thus, Paul counseled the church that a believer should not be united in marriage to an unbeliever unless the law of Moses regarding circumcision be done away among them.
