Is there a particular order in lighting candles on an advent wreath? In the Catholic tradition, is there a particular order in lighting the candles on an Advent Wreath?



If there is, why?

Which candle is lit first, and what order follows to the last candle? 

Where is the pink candle located in relation to the rest?
The advent wreath is an evergreen wreath with four candles. One is rose (pink) and the other three are purple.

Before lighting any candles on the wreath you should bless the wreath on the first Sunday of Advent.


Make the Sign of the Cross 1
The Father or head of the household then prays "Our help is in the name of the Lord." The family then responds "Who made heaven and Earth." Pray both verses if you are alone.
Optionally, read Isaiah 9:1-2, 5-6. These verses, and indeed the wreath itself, remind us that Christ is our light and his Birth brought us salvation.
Again, the Father prays:


  O God, by whose word all things are sanctified, pour forth thy blessing upon this wreath, and grant that we who use it may prepare our hearts for the coming of Christ and may receive from Thee abundant graces. Through Christ our Lord. [Response] Amen.

Sprinkle the wreath with Holy Water.
Optionally, if you are read to light the first candle for the first time you may to that now.
End with the sign of the cross.


Now you are ready to light the candles. The candles are not all lit at once. They are lit every night, adding one each week. For weeks when multiple candles are lit you must light them making the Sign of the Cross.


First make the Sign of the Cross.
Light the appropriate candles:


For the first week light only the top purple candle.
For the second week light the top purple candle and the bottom purple candle, in that order.
For the third week light the top purple candle, the bottom purple candle, and the left rose candle, in that order.
For the fourth week light all the candles starting at the top, moving to the bottom, then the left (the rose one), and finally the right.

Each week has an Advent prayer that is prayed after lighting the candles. The prayers are traditionally from the prayers that begin Mass for the beginning of that week. There is some variation. The following are from the traditional Latin Mass:


  
  Bestir, O Lord, Thy might, we pray thee and come; that, defended by Thee, we may deserve rescue from approaching dangers brought on by our sins, and being set free by Thee, obtain our salvation. Who livest and reignest, with God the Father, in the unity of the Holy Ghost, God, world without end. Amen.
  Stir up our hearts, O Lord, to prepare the ways of Thine only-begotten Son, that through His coming we may be worthy to serve Thee with purified minds. Who livest and reignest, with God the Father, in the unity of the Holy Ghost, God, world without end. Amen.
  Incline Thine ear to our prayers, O Lord, we beseech Thee; and make bright the darkness of our minds by the grace of Thy visitation. Who livest and reignest, with God the Father, in the unity of the Holy Ghost, God, world without end. Amen.
  Bestir, O Lord, Thy might, we beseech Thee, and come; and with great power come to our aid, that, by the help of Thy grace, that which is hindered by our sins may be hastened by Thy merciful forgiveness. Who livest and reignest, with God the Father, in the unity of the Holy Ghost, God, world without end. Amen.
  

Leave the candles burning for a time. Some families let them burn throughout dinner, or during a special devotional time they have set aside each evening.
Extinguish them later that evening.
Make the Sign of the Cross.


Explanation and Symbolism

Like nearly every other devotional, the Sign of the Cross starts and ends the lighting of the Advent wreath. Likewise, the wreath is lit in the same pattern. Lighting the Wreath is a nightly event that can be used as a way for Christians to intentionally keep Christ on their minds and in their hearts during the Advent season. The colors are not necessarily important, but they add extra symbolism.  Purple reminds us that this is a time of penance, fasting, and prayer. The rose candle is lit on Gaudete Sunday, the third Sunday in Advent, which is past the half way point to Christmas. The rose color gives us encouragement and reminds us that Christmas is indeed coming. During the Advent, the priest in your local parish may wear purple vestments during the Mass, but on the third Sunday, he may wear rose vestments. This is the same symbolism at work.

From your picture, the following looks to be the most appropriate arrangement and lighting order:





The candles on the wreath arranged as below make it easier to see the order of lighting tracing the sign of the cross.





1. The sign of the cross is made by moving your right hand up to touch your forehead, then to the lower middle chest, then to the left shoulder, then to the right. Some Eastern traditions move from right to left. While doing this you pray "In the name of the Father, and of the Son, and of the Holy Spirit. Amen." When on the word Father touch your forehead, and Son touch your chest, and Holy touch one shoulder, and Spirit touch the other shoulder.
