St. Dionysios has a contemporary exterior and an interior of splendor that dates back to the Byzantine era.

The design of  Byzantine style churches creates an atmosphere of worship, elevating the mind and soul of the worshipper towards heaven, towards the kingdom of the God he has come to worship and glorify.

A great deal of symbolism and meaning exists within the architecture of the Church. Everything in the building has a special meaning and purpose. It is the legacy of the Orthodox heritage and it is a link to our living Orthodox tradition. The architecture and art of the St. Dionysios church speaks volumes on the Orthodox faith and on the relationship that exists between God and man.

The symbols within the Church act as aids, as instruments that Orthodox Christians may use in their journey towards a personal relationship with the living Christ.

The narthex, is separated from the rest of the church by a wall and doors. It was to the narthex that the catechumens (those who were studying, but as yet uninitiated in the faith) would depart following the conclusion of the Service of the Catechumens in the Divine Liturgy. The exhortation for the catechumens to depart is still made by the Priest in the Divine Liturgy with the words "...the doors, the doors, in wisdom let us attend".

The central portion of the Church is the nave, from the Latin word "navis" which means ark or ship, because to the Orthodox, it is in this ark or ship of the church with Christ at the helm that they will be lifted into heaven. The most prominent feature of the nave and the highest point of the church is the dome. The dome is reserved for the most meaningful symbol of Orthodoxy, the image of the glorified Christ reigning on His heavenly throne, the icon of Christ Pantocrator .
The origin and meaning of this icon within the dome can be found in the Book of Revelations, "I am the Alpha and the Omega, saith the Lord Who is and Who was and Who is to come, the Pantocrator (Almighty)" [Rev. 1:18]. The design for the icon is described by St. John, "...and, behold, a throne was set in heaven, and one sat on the throne...and there was a rainbow round about the throne, in sight like unto an emerald. ...And I saw in the right hand of him that sat on the throne a book written within and on the backside, sealed with seven seals." [Rev. 4:2-12]

Beyond the nave, between the front-most pew and the altar of the Church is an area known as the Solea. It is here where all the sacraments of the church are administered. The distinctive features of this area include the pulpit in the northeast corner (far left corner, as one faces the altar), the chanter stand on the right and the throne of the Bishop.

The baptismal font in the area behind the pulpit is symbolic of a womb emphasizing that the sacrament of Holy Baptism is a rebirth, a resurrection of the infant into the life and faith of the Church. 

The throne of the Bishop is a historic remnant of the Byzantine empire where it was used by the royalty of the land. It has remained in the modern Orthodox church as the throne of the visiting royalty of the Church, the Bishop, the Archbishop or Patriarch. An icon of Christ the High Priest is depicted on the throne back.

The center of everyone’s attention as they sit in Church is the altar itself and the icon of the Virgin Mary in the apse of the altar. The altar is separated from the nave of the Orthodox church by a wall ornamented with icons. This icon screen or iconostasion has a dual meaning. First, it reminds the Orthodox of the partition which separates heaven (symbolized by the altar) and earth (as symbolized by the nave). Secondly, it serves as a reminder of the incarnation of Christ, because it was in the incarnation of Christ that heaven and earth met and in the architectural symbolism of the church, the icon screen is also a place where heaven and earth meet.

All Orthodox churches have icon screens and all conform to a general layout. The first icon panel to the right of the altar will always depict Christ. The second icon panel will always depict St. John the Baptist. The first icon panel to the left of the altar will always depict the Theotokos or God-bearer (the Virgin Mary with Christ child). The second icon panel on the left will vary from church to church as it depicts the patron saint of the Church. Here at St. Dionysios, you see St. Dionysios.

In addition to the arrangement of the icons, the icon screen contains three doors. The center or royal doors open into the altar and only members of the ordained clergy are allowed to pass through these doors.  It is through this door, also, that Christ passes every Sunday during the liturgy in the form of the Gospel, the Eucharist and in the person of the Priest, serving as a constant reminder that the only way into the altar, the only way into heaven, is through the doors which were opened by Christ. "I am the door; by me if any man enter in, he shall be saved, and shall go in and out, and find pasture." [John 10:9]  An icon of the Last Supper is depicted in the arch above the royal doors. 

A door to the far right opens into the vestry and a door to the far left opens into the Table of Oblation, where the prepatory service is held. These two side doors have icons of the Archangels Michael and Gabriel, who minister unto God and serve as guards of the Sanctuary.

The icons of the Church serve as constant reminders that the Orthodox Church is a Church of the living. We do not worship alone, but rather all the members of the Church Triumphant in Heaven, in other words, all the saints, martyrs and early Church Fathers are present with us each Sunday, praying and worshipping to God "for He is not a God of the dead, but of the living, for all live unto Him" [Luke 21:38]. 

A couple of points should be noted about the altar area. The first is that it faces the East, facing the rising sun which represents Christ the light of the world. In addition, the altar is elevated from the floor of the nave by a set of steps. The floor of the church symbolizes the earth. The altar symbolizes heaven which lies somewhere between the earth and the universe and is thus elevated by steps as a reminder of this relationship.

A gold tabernacle rests on the altar table (known as the "Holy Table") in the middle of the sanctuary. It contains the Holy Gifts, the Body and Blood of Christ which are consecrated each year on Holy Thursday and placed in the tabernacle. The Holy Gifts contained in the tabernacle are reserved for use in emergencies or visits to the sick and the infirm who cannot attend the liturgy, but they are not used during the liturgy. A votive light known as the "eternal light" burns constantly in front of the tabernacle as a reminder of the presence of Christ, the Light of the World in the tabernacle.

In addition to the tabernacle, a gospel book is always enthroned on the altar table and is ornamented with a gold or silver covering. On one side is depicted the Crucifixion of Christ and on the other side, His Resurrection. The gospel book contains excerpts from the four evangelists whose icons are depicted individually on each of the four outside corners.

The altar table symbolizes the tomb of Christ and is made of marble. Entombed within the altar itself is a relic of a Saint or Martyr which is installed during the church's consecration.

In the half-dome behind the altar in the apse of the Church is the icon of the Virgin Mary with the Christ child. This icon is known as the "Platytera Ton Ouranon", which translates into "more cosmic than the heavens" in reference to the fact that Mary contained within herself Christ, the Creator of the heavens. In the icon, Mary spreads her arms out wide as an invitation to all of us to come and accept her Son as our personal Savior and as a petition to us to allow Christ to work in our lives as He has in hers. 

The twelve disciples of Pentecost are depicted in the arch surrounding the Platytera.
