In nomine patri

Really? It's pretty cut and dry

Isn't is something like "In the name of the Father, the Son and the Holy Spirit"?

Yeah, the words sound pretty similar. If you know a Latin language, it's basically all right there.

You don't even need to know Latin, just English. Spiritu Sancti sounds like spirit sanctify (sactified spirit=holy spirit), filii=filial=child which more or less equates to son. Patri is patriarch is something father based=father

No.

Sarcasm, my friend.

Sorry, sometimes it's hard to tell
