put on
Lights to illumine the church, its sanctuary, and the altar, which must be lit during the liturgy and other prayers, even if services are held in daylight.
Inside the sanctuary two candle lamps must remain constantly lit: one in the eastern niche, and the other hanging down from the dome above the altar. During liturgical prayers two large candles are placed on candlesticks, one to the north and the other to the south of the altar.
Two wooden or metallic altar-candlesticks are either sides of the altar, and not upon it.
They refer to the two angels who were in the grave of our Lord.
