Toast Ideas for a First Holy Communion

Asking for a special prayer to be said is good, toasting? Not in any religion I know of. I have a poster I put together.
God's Promises
For God so loved world he gave us his only Son.
He that believes and is baptized will see the Lord's salvation.
Jesus Loves me.

Look inside a First Communion card, and maybe be inspired with something simple.

I agree, it's a holy day and a blessing would be better. I blessed my godson with a blessing based on his personality related to Bible men. Example: May you be like Joseph, who trusted and obeyed God even when it was difficult. Print it out and give him a vision and goal of what he can be for God (or she, as the case may be).

I was raised Catholic and I've never heard of a toast being given at a First Communion party, let alone a champagne toast. I think that a prayer might be more appropriate. (Or, like JustPlain Jo said, keep the toast simple.)

Oliver, you don't say whether this godchild is male or female. Either way, you know the child best. My advice? Keep it simple, short and sweet. Maybe something like "To (insert child's name.) (Insert a one-sentence observation about the child here.) May God richly bless you in all your endeavors as you learn and grow in His grace." Sorry if this isn't in the right format, I'm not a Catholic. You could also do a search for "First Communion Toast" and see what pops up.
