Q: In researching the history of our church, I’ve found that the building was originally dedicated in 1888. It was then expanded in 1927 and dedicated again. Finally in 2007, the building was renovated and a new altar dedicated.
So, which anniversary should we observe?
A: The anniversary celebration pertains to the dedication of the church. So you observe the 1927 date. From what you write, the 2007 ceremony pertained only to the altar, so its date does not pertain.
