The following is an excerpt I took out of Jimmy Akin’s book. This will give you an idea of what to expect:
Even before Mass starts, there are many things you see in church. Just as there are reasons for the different parts of the Mass, there are also reasons for these things. Holy water is placed, at the entrance of the church to remind us that through baptism we entered the Church. Holy water has been used since biblical days:
In an earthen vessel he shall meanwhile put some holy water, as well as some dust that he has taken from the floor of the Dwelling (Num. 5:17
[1]). Today people customarily bless themselves with holy water by making the sign of the Cross.
Those who are not yet baptized can do this as a way of looking forward to their baptism.
The many candles you find in the church, not only provide light, but also serve as symbols. They symbolize the teaching of Christ, “
the light of the world” (John 8:12), and they symbolize prayer, as prayers are offered up when each votive candle is lit. Another symbol of prayer you sometimes see in church is
incense. Because the smoke of incense floats upward, it has been used since biblical times to symbolize our prayers rising before God: ***Each of the elders held a harp and gold bowls filled with incense, which are the prayers of the holy ones ***(Rev. 5:8).
The statues, carvings, and pictures of saints and angels in the church go back to the Old Testament, when God commanded the Israelites to fill their places of worship with images of angels:
Make two cherubim of beaten gold for the two ends of the propitiatory,*** ***
fastening them so that one cherub springs direct from each end (Ex. 25:18-19). This was because the holy places symbolize heaven, and to remind men of this, God had them place representations of the inhabitants of heaven in them. Since Jesus has opened the gates of heaven, human souls now go there. That is why we now have statues of human saints as well as angels.
The main body of the church, where we all sit, is called the
nave. The other main part of the church is called the
sanctuary. It is the central place where the priests, deacons, and other ministers perform their roles at Mass. The Scriptures are read at a podium, called a
lectern. The central part of the mass is performed at the
altar, where the priest celebrates the Eucharist. Ever since biblical times, the altar has been referred to as "
the table of the Lord" (Mal. 1:7, 21; 1 Cor. 10:21), which is why offerings such as the Eucharist are made there. To show their reverence for the table of the Lord, people bow their heads when they pass in front of an altar.
[1] Holy water: water from the laver that stood in the court of the Dwelling.
