True, my education of Catholicism goes about as far as Wikipedia. That's where that list came from.
I did not know that Catholics did foot washing. I was pleasantly surprised to find out that they did. So if foot washing is a sacrament of the Catholic Church, why wasn't it on the 'list of seven sacraments' then? Maybe it's just cooler to have seven instead of eight?
And the description of Confirmation is all good and everything, and it seems to fit with Acts 2 somewhat, but I didn't see anything about the outward evidence of speaking in other tongues and so forth. (Yes, I know the purpose of Spirit Baptism is to provide the Christian with the power to be a witness, or martyr, but there is always an outward, observable evidence of this event in Scripture. Usually tongues and/or prophecy.)
Really, I just threw the reference to the 'Baptism with the Holy Spirit' in there to see if the Catholics are as anti-charismatic as some other folks. Overall, the mention of the Holy Ghost seemed to be pretty well received. That's good.
I happen to know Charismatic Catholics.
Foot washing on Holy Thursday is not a sacrament. It's a ceremony part of that day during Holy Week.
It's not a sacrament - it's a practice.
We have only seven sacraments.
