Some apostolics don't wear wedding rings. Some do.
Those that don't wear rings have everything from a personal conviction to respect for the convictions of others to a conviction that wearing rings are a sin for everybody.
Those that do wear rings can do so in simplicity or in obsession. They can cause others to stumble with jealousy or a spirit of competition.
It looks to me like the stances on wedding rings are cultural - in both camps. Those that don't wear rings inherited their preference from their church culture, and those that do wear rings do so in recognition of the prevailing culture.
I know the admonition against costly array,
so let us just consider the case of a simple wedding band - the nationally-accepted way of signifying marital status in our culture.
1 Timothy 2:8
I will therefore that men pray every where, lifting up holy hands, without wrath and doubting.
9 In like manner also, that women adorn themselves in modest apparel, with shamefacedness and sobriety; not with broided hair, or gold, or pearls, or costly array;
10 But (which becometh women professing godliness) with good works.
11 Let the woman learn in silence with all subjection.
12 But I suffer not a woman to teach, nor to usurp authority over the man, but to be in silence.
13 For Adam was first formed, then Eve.
14 And Adam was not deceived, but the woman being deceived was in the transgression.
15 Notwithstanding she shall be saved in childbearing, if they continue in faith and charity and holiness with sobriety.
1 Peter 3:2
While they behold your chaste conversation coupled with fear.
3 Whose adorning let it not be that outward adorning of plaiting the hair, and of wearing of gold, or of putting on of apparel;
4 But let it be the hidden man of the heart, in that which is not corruptible, even the ornament of a meek and quiet spirit, which is in the sight of God of great price.
And I Peter talks about adornment with gold (although this one if taken literally also teaches against women wearing clothing) as a means of enticing a wayward husband to attend church.
So I can see that we have bible that discourages women from indulging in the vanity of excessive or expensive decoration. But mainly it is about using such decoration as a means of attracting attention to self or to Christianity - not an outright ban in and of itself. But it doesn't mention rings, it doesn't mention men, and it doesn't mention an outward cultural indicator of marital status.
As an aside, I think it is more useful for men to wear wedding rings, because women tend to be more mindful of propriety when they are "in the market" for a husband. The sight of a ring tells a woman she needs to visit the next aisle.
So here is the question on my mind this morning:
If you don't wear a wedding ring, what is the reason, what is the biblical verse or principal that backs it up?
If you do wear a wedding ring, where do you find biblical support for your practice?
I'd like to pre-empt the wise guys by saying that the response "because I'm not married" is hereby deemed null, void, uninteresting, obvious, and dull. If you are unmarried, answer in the hypothetical with your current beliefs, please.
