The symbolism of the advent wreath centers on the Coming of the Lord. The candle stands for Christ. The circle is a symbol of eternity (Heaven and hell are the only options). The evergreen is for eternal life. Green stands for hope and its renewal. A blessed candle always represents Christ. Violet and rose call us to penance and joy. Each candle also represents one millennium of hope in the Messiah. Pray the psalms, as they are excellent means to nurture hope.
