I need help translating something into Latin

Well, my US History teacher wants us to do an assignment on 'something we believe in'. I decided to write a song about hate and discrimination going away(keep dreaming, right?). But, I'd like the chorus to be in Latin. Here's what it is in English.

Let cry the Angels
Let weep the Saints
And wonder if the hour's too late
To erase all the pain and hate

I'd appreciate your help!
