That they all may be one

That they all may be one is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand That they all may be one rather than just read about it. In short: "That they all may be one" (Greek: ἵνα πάντες ἓν ὦσιν, ina pantes hen ōsin, Latin: Ut omnes ūnum sint) is a phrase derived from a verse in the Farewell Discourse in the Gospel of John (17:21) which says: that they may all be one. As you, Father, are in me and I am in you, may they also be in us, so that the world may believe that you have sent me.

Key takeaways

That they all may be one belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect That they all may be one to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of That they all may be one from memory before moving on to harder problems.

Reference excerpt

that they may all be one. As you, Father, are in me and I am in you, may they also be in us, so that the world may believe that you have sent me.

Significance and uses The phrase forms the basis of several ecumenical movements and united and uniting denominational traditions. It is also a common sermon topic on church unity. The phrase is the official motto of the Church of South India. The Latin version, Ut Omnes Unum Sint, is the motto of the World Student Christian Federation, the University of Mainz, the United Church of Canada and the YMCA. The United Church of Christ has the same motto except for a change in the place of one word: "That they may all be one." The phrase is also the motto of the Graymoor Friars (the Society of the Atonement). They have used this phrase for over 100 years to describe the apostolate of the order. The Society of The Atonement started the worldwide observance of "The Church Unity Octave." The work of this Roman Catholic, Franciscan, religious order is Ecumenism. Pope John Paul II published an encyclical under the Latin Vulgate form of this title, Ut unum sint. It is the motto of the Wilding family, who founded Claires Court School, Maidenhead, England, and has been incorporated into the school badge since 1993, when the school acquired Maidenhead College, adding girls education to the school. It is also one of two mottoes of Spalding Grammar School in Lincolnshire, England. It is the motto of Achimota School located in Accra, Ghana and St. Louis Senior High School in Kumasi. Both Strathmore School and Strathmore University in Nairobi, Kenya. St. Paul's School in Rourkela Orissa, India also bears this motto on its Badge. It is also the motto of the Presbyterian Church of Ghana and the Grand Lodge of Ghana. Igbobi College, located in Lagos, Nigeria, also bears this motto on the school crest/badge.

Worked examples

Example 1 — a first encounter with That they all may be one

Start with the simplest possible case. Write down what That they all may be one claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to That they all may be one before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about That they all may be one ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of That they all may be one

In research: That they all may be one appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses That they all may be one in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: That they all may be one is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bible stubs, Gospel of John, New Testament words and phrases, so understanding it makes those chapters shorter.
In everyday life: Look for That they all may be one outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
