Congratz!
I was installed as Junior Deacon in 2017. I made sure I was done with the MC lecture before I was to be installed as SD in 2018. Unfortunately, our JW had to step down for health reasons mid-way through 2017. Our Lodge has a very healthy line so we jumped up a chair for the remaining months. We have been sitting in advanced chairs since October of this year and it is a fun chair. The downside is that I’m envious of you! I’m going to be skipping SD and going straight to Junior Warden in 2018. I will only be doing the second section of FC as Senior Deacon come 2018.
My point is: The senior deacon’s place is probably the best seat in the house after being Master (and I have yet to get there. It’s what I’ve been told by PMs who have occupied both chairs.) Enjoy it. Have fun with it. Learn your parts because you are the most important piece of the puzzle for degree work outside of the candidate and Master.
Take pride in attending to the Altar. All eyes are on you.
