The REG defines offerings
here.
Offering
Several Redemption® cards specifically reference offerings. The offerings in Redemption® refer to those done on the altar. The following cards refer to offerings:
• Day of Atonement (Pi), Joiada, Son of Eliashib (FF), and Altar of Burnt Offering (Pi)
The following Redemption® cards are considered offerings:
• Burnt Offering (Pi), Fellowship Offering (Pi), First Fruits (Pi), Grain Offering (Pi), Guilt Offering (Pi), Scapegoat (Pi), and Sin Offering (Pi)
I believe at one time it was further clarified that "done on the altar" was intended to mean "done on the Alter of Burnt Offering" If my memory is correct, that is one reason I was given that Burning Incense is not considered an "offering" for Redemption purposes.
I share all that so everyone knows the current ruling. Feel free to discuss the implications of broadening the definition if you'd like. I don't think that's a very fruitful discussion to take to the other side of the boards right now. There are several "open" topics already that are probably a bit more important. I'd like to see the elders resolve those before Nationals and this would simply be a distraction.
