"In hoc signo vinces" is a Latin rendering of the Greek phrase "en touto nika", meaning "with this as your standard you shall have victory" in English.
Khorúgv (Russian: Xоругвь, sometimes translated as gonfalon), is a religious banner used liturgically in the Eastern Catholic and Eastern Orthodox Churches.
The khorugv or banner consists of an icon of Christ, the Theotokos or a saint, either painted or embroidered on a rectangular piece of cloth. The cloth is often pointed or swallow-tailed, or has several streamers coming down from it. The banner often has two or three tails on it, each terminating in a tassel, and may be fringed around the edges. It is suspended from a crossbar which is attached horizontally to a long vertical pole (see the article Gonfalon for a picture). The finial at the top of the pole is usually a cross. More rarely, banners can also be made of metalwork, or carved out of wood.
In hoc signo vinces
The labarum (Greek: λάβαρον) was a vexillum (military standard) that displayed the "Chi-Rho" symbol ☧, formed from the first two Greek letters of the word "Christ" (Greek: ΧΡΙΣΤΟΣ, or Χριστός) — Chi (χ) and Rho (ρ). It was first used by the Roman emperor Constantine I. Since the vexillum consisted of a flag suspended from the crossbar of a cross, it was ideally suited to symbolize the crucifixion of Christ.
Ancient sources draw an unambiguous distinction between the two terms "labarum" and "Chi-Rho", even though later usage sometimes regards the two as synonyms. The name labarum was applied both to the original standard used by Constantine the Great and to the many standards produced in imitation of it in the Late Antique world, and subsequently.
In hoc signo vinces (reconstructed Latin pronunciation [ɪn hoːk ˈsɪŋnoː ˈwɪnkeːs], ecclesiastical pronunciation [in ok ˈsiɲo ˈvintʃes]) is a Latin rendering of the Greek phrase "ἐν τούτῳ νίκα" en touto nika, (Ancient Greek: [en tǒːtɔːi̯ níkaː]) and means "in this sign you will conquer".
According to legend, Constantine I adopted this Greek phrase, "ἐν τούτῳ νίκα" (in this, win) as a motto after his vision of a chi rho in the sky just before the Battle of Milvian Bridge against Maxentius on 28 October 312. The early Christian symbol consists of a monogram composed of the Greek letters chi (X) and rho (P), the first two letters in the name Christ (Greek: Χριστός). In later periods, the christogram "IHS" both stood for the first three letters of "Jesus" in majuscule Greek lettering (ΙΗΣΟΥΣ) and "in hoc signo" from the legend.]citation needed[
Sigma Chi (ΣΧ) is one of the largest Greek-letter social fraternities in North America with more than 240 active chapters in the United States and Canada and more than 300,000 initiates. Sigma Chi was founded on June 28, 1855 at Miami University in Oxford, Ohio when members split from Delta Kappa Epsilon. The founding members were: Benjamin Piatt Runkle, Thomas Cowan Bell, William Lewis Lockwood, Isaac M. Jordan, Daniel William Cooper, Franklin Howard Scobey, and James Parks Caldwell. Sigma Chi is a part of the Miami Triad, along with Beta Theta Pi and Phi Delta Theta.
According to the fraternity's constitution, "the purpose of the fraternity shall be to cultivate and maintain the high ideals of friendship, justice, and learning upon which Sigma Chi was founded."
