Holy Trinity in the context of "One God"

Hypostasis (plural: hypostases), from the Greek ὑπόστασις (hypóstasis), is the underlying, fundamental state or substance that supports all of reality. It is not the same as the concept of a substance. In Neoplatonism, the hypostasis of the soul, the intellect (nous) and "the one" was addressed by Plotinus. In Christian theology, the Holy Trinity consists of three hypostases: that of the Father, that of the Son, and that of the Holy Spirit.

Making the sign of the cross (Latin: signum crucis), also known as blessing oneself or crossing oneself, is both a prayer and a ritual blessing made by members of some branches of Christianity. It is a very significant prayer because Christians are acknowledging their belief in the triune God, or the Holy Trinity: God the Father, God the Son and God the Holy Spirit. There are three variants of the sign of the cross, including a large sign of the cross made across the body, a small sign of the cross traced on the forehead or objects, as well as a lesser sign of the cross made over the forehead, lips and heart.

The use of the sign of the cross traces back to early Christianity, with the third-century treatise Apostolic Tradition directing that it be used during the minor exorcism of baptism, during ablutions before praying at fixed prayer times, and in times of temptation.

Marian columns are religious monuments depicting the Virgin Mary on the top, often built in thanksgiving for the ending of a plague (plague columns) or for some other reason. The purpose of the Holy Trinity columns was usually simply to celebrate the church and the faith, though the plague motif could sometimes play its role in their erection as well. Erecting religious monuments in the form of a column surmounted by a figure or a Christian symbol was a gesture of public faith that flourished in the Catholic countries of Europe, especially in the 17th and 18th centuries. Thus, they became one of the most visible features of Baroque architecture. This usage also influenced some Eastern Orthodox Baroque architecture.

The Caracas Cathedral or Metropolitan Cathedral of Saint Anne is the seat of the Roman Catholic Metropolitan archdiocese of Caracas, located on the Plaza Bolívar in Caracas, Venezuela. Its chapel of the Holy Trinity is the burial site of the parents and wife of Simón Bolívar. The Nuestra Senora de Venezuela y Santa Ana is a square (cuadra) situated between the cathedral and the central plaza, which is walled on three sides, but open to the east where it faces the cathedral.

The Trinitarians, formally known as the Order of the Most Holy Trinity and of the Captives (Latin: Ordo Sanctissimae Trinitatis et Captivorum; abbreviated OSsT), is a mendicant order of the Catholic Church for men founded in Cerfroid, outside Paris, in the late 12th century. From the very outset, a special dedication to the mystery of the Holy Trinity has been a constitutive element of the order's life.

Papal documents refer to the founder only as "Brother John", but tradition identifies him as John of Matha, whose feast day is celebrated on 17 December. The founding-intention for the order was the ransom of Christians held captive by Muslims, a consequence of crusading and of piracy along the Mediterranean coast of Europe.

Protestant theology refers to the doctrines held by various Protestant traditions, which share some things in common but differ in others. In general, Protestant theology, as a subset of Christian theology, holds to faith in the Christian Bible, the Holy Trinity, salvation, sanctification, charity, evangelism, and the four last things.

Various Protestant denominations differ in their doctrine, with churches teaching either Wesleyan-Arminian theology, Reformed theology, or Baptist theology. Other evangelical bodies, such as the Lutheran Church–Missouri Synod, Presbyterian Church in America and the Evangelical Friends Church International may subscribe to what they see as the orthodox theology espoused by their historic tradition, such as Lutheranism, Presbyterianism or Quakerism respectively.

The Order of the Ship (French Ordre de la Nef) was a secular order of knighthood in the Kingdom of Naples founded and dedicated to the Holy Trinity by King Charles III of the House of Durazzo on 1 December 1381 and no longer active by 1386.

Charles III was crowned King of Naples in the Castel Nuovo in Naples on 25 November. During the festivities that followed, he inducted seven or eight knights into a new order of his own creation at a ceremony in the great chapel of the Castel Nuovo on 1 December. In this he was probably imitating the founding of the Order of the Knot by King Louis I twenty years earlier on 25 May 1352, the same day as his coronation. Although there were present in Naples men who would have remembered the founding of the Order of the Knot, but it is unlikely that Charles sought to revive the Order of the Knot, defunct since Louis's death in 1362, since Louis's heirs were Charles's rivals for the throne.
