Why do you /we need an altar to do that? Jesus managed quite well with a low table.
Is there any NT evidence that such things were in use?
Probably not, but then again, there is no evidence that such things weren't in use either. As far as "Jesus managed quite well with a low table", well, a narrow table is exactly what the altar at my church is. It's not low, but then if it was our pastor would have to bend over in kind of an unseemly manner to take the elements of communion off of it. ;)
Going back to whether there is or isn't NT evidence that such things were in use...this brings up again the area of whether we will use only what the NT mentions...for instance...there is no mention of using musical instruments during worship in the NT either...and at least one denomination, The Church of Christ, do not have instruments in the church.
I don't know if Church of Christ have altars...where's Jeff (StoveBolts) when we need him? :D
If you are of a mind that only that which is specifically mentioned in the NT should be used during worship, then one would expect that such things like altars, baptismals, crosses and crucifixes, pews, organs, guitars, pulpits, and even, if we want to be completely intellectually honest about it, microphones and amplifiers and church buildings themselves must not be used.
I tend to go more with the idea that only things that are specifically forbidden should be forbidden and things that are specifically mentioned must be included...and that we have a lot of freedom there is freedom in the "things not mentioned".
The ones I've seen have candles, collection plates, 'wafers', considerable amounts of gold or something similar, and I really don't know what else. Can all this be right, I ask myself?
Candles are pretty traditional in worship and this goes back to the Old Testament as well. I know that some churches put the monetary offerings on the altar as they are our physical offerings...our pastor doesn't, he feels that nothing but the Scriptures and elements for communion (which wafers "unleavened bread" are) and the crucifix should be there...and most of the time the collection plates are gold toned.
There is a word...adiaphora...which means that in things that are not essential, we should allow freedom. I think what elements different churches view as important to their worship services is a good example of adiaphora.
But we are to confess our sins to Christ, and I can't easily recall anywhere that an altar is mentioned in the process.
No, we don't need an altar to confess our sins to Christ...but, if those low benches or pews, what passes as "altars" in churches like the Nazarene Churches and the Assemblies of God serve the function of being the place folks can physically bring their burdens of sin and prayer to God, why not? Are we not to worship God in both body and spirit?
So why do it? Just look at Catholic, Anglican, Eastern Orthodox practice: don't you ever wonder how much connection with truth is being exhibited there?
You can add Lutheran in that mix as well, as our worship services tend to be very similar. And, as I am currently learning about the liturgy I am very uplifted with how much truth is in the liturgy. If you want to discuss it, I'll be happy to share how much I've learned. For now I'll say that there is this quote, "We learn what the Church believes by the way in which she worships." Going through the liturgy one can learn that in our church we believe that we have a need to confess, that God forgives all who sincerely confess, that we know God as Father, Son and Holy Spirit, that God is a God of mercy, that He is a God who listens to the prayers of His people, that His word is divinely inspired and profitable for us to listen to even today, that Christ gave His Body and Blood for the remission of our sins......do you see any connection with any truth in this? I certainly do!
And then there's the question of 'priests', 'bishops', 'archbishops' and I have no idea how many other ranks there are. I see no evidence in the NT of such, but I'm prepared to be shown.
There were recognized "offices" in the early church
Bishop - Greek word "episkope" defined as an overseer of the church. 1 Timothy 3:1 "It is a trustworthy statement: if any man aspires to the office of overseer, it is a fine work he desires
to do."
Elders - Greek word "presbyteros" This word had application for the Jews as well as the Christians but it is a "presiding" office. Acts 14:23 speaks of "appointing elders".
The elders and bishops were generally ordained (and yes, that word can be found in the New Testament as well) by the Apostles and by other elders. For instance, Timothy was ordained as the first Bishop of Ephesus. The office was different and of higher rank than that of pastor.
