What are the christian symbols for confirmation and marriage?
There aren’t any actual ‘Christian symbols’ as such (if you’re thinking of things like the cross or the icthus) for those- but you’d probably find a dove or flame used quite a lot (as they’re often used to represent the Holy Spirit) on things like Confirmation cards and anything that signifies unity or eternity could be used for marriage (like the rings- the circle representing eternity). The dove is also quite common as a symbol of peace- and it often appears on wedding cards.
