669. In Christianity the two sacraments, baptism and the Holy Supper, are actually like two royal insignia on a monarch's scepter. If we do not know what function these sacraments perform, however, they seem to us like two figures carved in ebony on someone's walking stick.

In Christianity the two sacraments can also be compared to two rubies or precious garnets on an emperor's robe. If we do not know what function they perform, however, they seem to us like a pair of cheap carnelians or pieces of cut glass on someone's overcoat.

If the functions of the two sacraments were not revealed through the spiritual meaning, guesses about them would spread, but those guesses would have no more value than the pronouncements of people who read the stars or people in ancient times who read omens in the flight of birds or in entrails.

The functions of the two sacraments can be compared to a church building that because of its extreme age has sunk into the ground; even the roof is completely covered with debris. People young and old walk or ride in carriages or ride horses over it without any idea that hidden underfoot there is a beautiful church with altars of gold, interior walls of silver, and decorations of precious stones. The only way to dig these treasures up and bring them to light is through the spiritual meaning, which is being disclosed today for the new church and its worship of the Lord.

The sacraments can be compared to two temples, one of which is built on top of the other. In the lower temple someone is preaching the good news of the Lord's new coming, and also the good news that we are regenerated and saved by the Lord. From this temple, around its altar, there is a way to go up to the higher temple. There the Holy Supper is being celebrated and there is a passageway to heaven where the Lord is welcoming us.

The sacraments can also be compared to a tabernacle. After we enter it a table appears on which the showbread has been carefully arranged. That tabernacle also contains a golden incense altar, and in the middle, a lampstand with its lamps lit, allowing all these things to come into view. Eventually, if we allow ourselves to be enlightened, the veil to the most holy place opens, where in place of the ark that held the Ten Commandments, the Word is kept. Above it there is a mercy seat, protected by angel guardians that are made of gold.

These are representations of the two sacraments and their functions.

166. 2. These three, the Father, the Son, and the Holy Spirit, are three essential components of one God. They are one the way our soul, our body, and the things we do are one. In any given thing there are general essential components and there are also specific essential components. The general and specific components combine to make one essence.

In our case, our general essential components are our soul, our body, and the things we do. These three components combine to make one essence, as you can see from the fact that one component comes from and exists for the other in an unbroken chain. We begin from our soul. The soul is the essence of the semen that originates us. Our soul not only initiates but also sequentially produces the features of our body. Then there are the things we do, which come from both our soul and our body. Because one of these components produces another, and therefore the subsequent components are grafted onto and connected to those that came before them, it follows that these three components share one essence. This is why they are called the three essential components.
