In relation with the Church of Jesus Christ, the Master Jesus instituted two external signs as sacraments that must be observed by His Church: baptism and the Lord's Supper, otherwise called the Lord's Supper.
In the New Testament, these two sacraments are given using ordinary things of life such as water, bread, and wine they consecrate as signs of great gospel truths. Everyone who accepts Jesus Christ as Lord and Saviour with a good conscience is adopted into the house of God where he dwells by baptism and the Lord's Supper. Those who are in the Church and who do not go through these two acts are unknown to God. Those who believe manifest it by these two acts to confirm their membership.
