The feast day of St Francis Xavier this year is Tuesday 3 December (in both the older and latest general calendars)  

 
Cur ígitur non amem Te,
o Jesu amantíssime?
Non ut in cælo salves me,
aut ne ætérno damnes me,
nec præmii ullíus spe;
sed sicut Tu amásti me,
sic amo et amábo Te,
solum quia Rex meus es,
et solum quia Deus es. Amen.

Why then would I not love you,

O Jesus, most to be loved?

Not that you may save me in heaven,

or lest you damn me eternally,

and not in hope of any reward.

But just as you have loved me,

so I love and will love you,

only because you are my king

and only because you are God. Amen
