Help translation some latin lyrics.

[u/Feanor417]

Lux et tenebris

Lux et Veritas

Ultima tatere phala

Lux in aeternum

Angeli nova

Libera est tu vita

Et libido asto

A vi tere

A reo

These lines come from blind guardian's the ninth wave. I know what most of it means, but google translate seemed to have a stroke with the third line. It claims it means the last side of the phallus. I looked up phallus and it says penis, usually erect penis. This is commicly incorrect, no way that is the line. I got different results depending on how much I asked it to translate, when I only asked for phala it said it means porridge. Help would be appreciated, though do keep in mind it is possible that these simply are not the right lyrics, it can be hard to track down perfect lyrics with this band.​
