My church’s youth group is going to Mexico on a mission trip next week. One of our themes is John 13:34 - Love one another as I have loved you. Can someone translate this for me? Thanks!
There is an Alta Vista language translator. Maybe do a Google search.
That is the full verse; what you had in your OP was the very brief version (e.g. from English Standard Version, A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another.)
Pretty good, except it may sound funny to Mexican ears because it’s Castilian Spanish. (Or maybe not – it’s possible that they’re used to lno’s version, just as many American Christians are used to the language of the King James Bible.) All the same, here’s a slightly more Mexican-idiomatic translation that I found on a couple of other pages:
A friend at work gave me:
Amencen los unos con los otros…Como yo los he amado…
Is that right? I just need a simplified version for kids. 
Thanks in advance again. 
My Spanish isn’t perfect, but that means love with the others, doesn’t it? Fretful Porpentine’s translation sounds awfully good.
Yeah it does - I was hoping for the simplified version though. It’ll be going on a puzzle for kids.
This sounds like an orgy.
I would suggest:
Amencen como yo les he amadao
This is simpler, but it may be understood as love yourself as I have loved you.
or
Amencen unos a otros como yo les he amado
This is more specific.
It´s ámense, not amencen.
I don´t know what kind of puzzle it is - but wouldn´t the kids rather recognize the quote (if they´ve already heard it a few times) than a simplified version?
I´d go with Fretful Porpentine´s version, but if you want to keep it simple, it´s:
ámense los unos a los otros cómo yo los he amado - but it´s not really much shorter or simpler than the original, I think.
