A conference of the Church is held in Kirtland, with a solemn assembly held on April 6 for the purpose of the washing of feet, anointing, and receiving various instructions. Other meetings are held by different quorums, leading up to a general meeting on April 6. The seventies who have previously been ordained high priests are released from their callings as seventies, and new seventies are called and ordained. Joseph explains that the Melchizedek Priesthood is "no other than the Priesthood of the Son of God." He also says, "After all that has been said, the greatest and most important duty is to preach the Gospel." He talks about "embarrassment, of a pecuniary nature," stating that $6,000 is still needed by the members in Missouri, and $13,000 is needed for the debts caused by the building of the Lord's House in Kirtland. The sacrament of the Lord's Supper is passed, using bread and water. This is the first mention of water being used in the sacrament instead of wine.
