The Blood of Christ

[The Leaven – exploring the relationship between science and religion (cont)]

In the molecular era, it is now known that fermentation is not only responsible for the leavening of bread but it is also the principle process in brewing and wine making. It ‘s worthwhile taking time to consider how wine was perceived in the biblical era and how its use is viewed in current religious ceremony. Present society now understands that the intoxicating agent of wine is alcohol, a by-product of the yeast fermentation process. It is also understood that unfermented fresh grape juice, or must, is relatively free from alcohol. These principles were not understood by ancient societies, as the knowledge behind the biology of fermentation did not exist. When leaven is used in making bread it is viewed as an impurity and therefore omitted from many sacrificial ceremonies. In contrast wine, which is also produced by a similar fermentation process involving yeast, was not only permitted in sacrifices but was sometimes a principal component.

Wine production occurs naturally in the environment. Grape skins are covered with yeasts and bacteria, mainly members of  the yeast family Saccharomyces. When grapes are crushed they ferment, especially in warm climates as yeast fermentation occurs between 20 and 40°C with an optimum growth temperature of around 30°C. The main fermentation is aerobic and takes a few days. It then  continues anaerobically at a slower rate for some time. When fermentation is complete the resulting wine is racked from the sediment, a substance containing precipitated organic matter and yeast. In the biblical era wine is produced in animal skins or in jars designed specifically for the fermentation process. In the New Testament the fermentative characteristics of wine were well recognised as is evident in some of the passages. The following parable uses the properties of fermentation to describe how a flexible way of thinking was needed to accept new and fresh ideas:

Nor does anyone pour new wine into used wineskins, for the skins will burst, the wine will pour out, and the skins will be ruined. Instead, new wine is poured into fresh wineskins, and both will keep in good condition
[Matt. 9.17; Mk. 2.22; Lk. 5.37]

Wine is not referred to in the Bible as leaven or unleavened although it does feature in sacrifices and rituals. In the Old Testament it is used in large quantities as part of a daily sacrificial offering that also included animals and unleavened bread [Ex.29.38-46; Num. 28.1-8]. Wine is also offered on the Sabbath and on the first day of the month, where the quantity varies depending on the type of animal used in the sacrifice . Most notably, wine was offered in the daily sacrifice during the festival of the unleavened bread:

The proper wine-offering is two measures of wine with each bull, one and a half measures with the ram, and one measure with each lamb.
[Num. 28.9-15]

It does seem, in respect to sacrifices, that leaven was not associated with wine in the same way as it is associated with bread. Perhaps this is because the process of wine production was not as accessible to the overall population as bread making, therefore it is less likely to be used in domestic ceremonies due to lack of availability. Also as wine is intoxicating and bread is not,  perhaps fermentation in bread was simply thought of as a different process. In addition wine is rarely associated with food poisoning although it is possible for some microbial toxins to be found in wine. Generally if wine becomes contaminated during fermentation it is undrinkable and becomes cloudy, perhaps at this stage it might have been viewed as impure and corrupt. Pathogenic microbes usually require an optimal pH similar to that found in animals, this is why ethanol with a high pH is normally used in sterilisation. In fact this could be the reason why alcohol, similarly to salt, is used in these sacrifices, for its ability to sterilise and remove contamination.

There may have been numerous reasons why ancient communities may have performed rituals and sacrifices. Perhaps they needed to address fear, uncertainty, need, respect or gratitude. Whatever the reasons, rituals are still a part of modern life and sacrifices can still form important components to some religious ceremonies, although they are more likely to be symbolic and just a distant reminder of our pagan ancestry. In the era of the Old Testament, sacrifices were a major preoccupation of Hebrew life. It seems evident that they were carried out to avoid uncertainties and as a form of thanksgiving. They were often accompanied by rituals that were performed according to specific instructions outlined in the books of the Old Testament:

When anyone offers an animal sacrifice, it may be one of his cattle or one of his sheep or goats. If he is offering one of his cattle as a burnt-offering, he must bring a bull without defects. He must present it at the entrance of the Tent of the Lord’s presence so that the Lord will accept him. The man shall put his hand on its head, and it will be accepted as a sacrifice to take away his sins.
[Lev. 1.2-4]

The Old Testament is derived from at least four literary sources that span over several decades from 950 to 587 BC. Unavoidably, some information may have been lost or contorted through subsequent translations but the most authoritative form was thought to be the Pentateuch, a word that derives from the Greek language and meaning five scrolls. The Pentateuch was adopted around 400 BC and consisted of the five books: Genesis, Exodus, Leviticus, Numbers and Deuteronomy. The Hebrew word for these five books is the Torah, meaning law or teachings.

The Pentateuch mainly describes the story of Moses: his birth, teachings through a covenant with God and ending with his death. It begins with the book of Genesis. This book provides an in depth history of Moses’ pedigree starting with an account of primeval beginnings to how his ancestors came to live in Egypt. The next book, Exodus, recounts the most important event in Israel’s history, the escape from servitude by its people. The Hebrews were led from Egypt by Moses. While in exile from Egypt for killing a slave master, Moses formed a covenant with God. Through using Moses as a mediator, God provided laws and commandments that Hebrews had to follow to avoid returning to servitude. Leviticus, the third book, contained the rules and regulations for performing religious ceremonies in order to honour God. It includes comprehensive details of how sacrifices are to be performed.

The following are the regulations for repayment-offerings, which are very holy. The animal for this offering is to be killed on the north side of the altar, where the animals for the burnt-offerings are killed, and its blood is to be thrown against all four sides of the altar. All its fat shall be removed and offered on the altar: the fat tail, the fat covering the internal organs, the kidneys and the fat on them, and the best part of the liver. The priest shall burn all the fat on the altar as a food-offering to the Lord. It is a repayment-offering. Any male of the priestly families may eat it, but it must be eaten in a holy place, because it is very holy.
[Lev. 7.1-6]

The book of Numbers deals with the story of the Hebrews after they left Mount Sinai. It includes details of two censuses taken by Moses, one taken of those surviving the exodus on departing Mount Sinai and another taken a generation later. The final book, Deuteronomy, is a summary of Moses achievements as the people prepare to occupy Canaan. The main objective of Deuteronomy seems to be in encouraging the people to give thanks to God. This takes the form of a liturgy delivered by Moses to celebrate future harvests:

After you have occupied the land that the Lord your God is giving you and have settled there, each of you must place in a basket the first part of each crop that you harvest and you must take it with you to the one place of worship.
[Deut. 26. 1-3]

Interestingly, this type of harvest thanksgiving has been conserved through religious tradition and is still carried out today.
