To answer the title question: I’m happy with the Guardian Angel God gave me!
Now on to more serious stuff.
First of all, God gives every person, Catholic and non-Catholic, a Guardian Angel. So you can’t trade in your Guardian Angel for another. He’s closer to you than your shadow, and he’s going to stick with you whether you want him to or not.
Would you like your guardian angel to appear on a weekly basis and gently chat to you about the good and bad you did during the week or an angel that would reprimand you for sinning?
NO. One should NEVER wish to see one’s Guardian Angel. St. Paul, St. Ignatius of Loyola and all the masters of the spiritual life say that the Evil One can disguise himself as an angel of light.
I just wondered how you would want him to help you?
I want him to help me the way God wants him to help me.
St. James in his Epistle talks about being of two minds. I don’t remember the exact quote but it’s in there.
If through the grace and mercy of God I get to heaven, I want to thank God for my salvation, my Catholic Faith, giving me His Mother to be my mother, His foster-father to be my foster-father, all the Saints and Angels who ever prayed for me and helped me, AND my Guardian Angel.
