Sure lets baptize them in the womb too, and make 2 year olds priests and pastors. Actually I like that idea for those who can’t understand the bible and yet claim to follow Jesus. All church leaders must be under the age of 8, brilliant!
Well, #1...when I hear you complain about the Mormons making 12 yo part of their Aaronic priesthood...well, then I'll know this may really be of concern to you.
#2...It's almost as if you haven't dug into your Bible very thoroughly:
For example, these Passages (note the bold-face):
4 As you come to him, the living Stone—rejected by humans but chosen by God and precious to him— 5 you also, like living stones, are being built into a spiritual house to be a holy priesthood, offering spiritual sacrifices acceptable to God through Jesus Christ. 6 For in Scripture it says: “See, I lay a stone in Zion, a chosen and precious cornerstone, and the one who trusts in him will never be put to shame.” 7 Now to you who believe, this stone is precious. But to those who do not believe, “The stone the builders rejected has become the cornerstone,” 8 and, “A stone that causes people to stumble and a rock that makes them fall.” They stumble because they disobey the message—which is also what they were destined for. 9 But you are a chosen people, a royal priesthood, a holy nation, God’s special possession, that you may declare the praises of him who called you out of darkness into his wonderful light. (1 Peter 2)
Who do you think "you" who are the "chosen people, a royal priesthood, a holy nation" are?
What? You think married Peter was referencing a "nation" of batchelor priests?
Tell ya what: Google "priesthood of all believers"
Here's another verse:
To him who loves us and has freed us from our sins by his blood, 6 and has MADE US to be a kingdom and priests to serve his God and Father—to him be glory and power for ever and ever! (Revelation 1:5-6)
