Did the Pope say "allow ourselves to be smitten" by the love of Jesus?

Last night's "Smitten by his love" post brought email from ddh:

Your suspicion that the Pope did not say "smitten" is correct. After an introductory paragraph in Portuguese, the Pope switched to his native Spanish and said, according to the Vatican:

Pero la Cruz invita también a dejarnos contagiar por este amor, nos enseña así a mirar siempre al otro con misericordia y amor, sobre todo a quien sufre, a quien tiene necesidad de ayuda, a quien espera una palabra, un gesto.

I translate this sentence as:

But the Cross also invites us to let ourselves be infected by this love, it teaches us always to look at the other person with mercy and love, especially to the one who suffers, the one who needs help, the one who awaits a word, a gesture.

So, what he really said was "contagiar" or "to be infected." By the way, most native Portuguese speakers can understand Spanish without great difficulty, although not perfectly. I think for English speakers the effect is akin to listening to a Robert Burns poem.

Who is in a position to confirm whether the effect of Spanish on native speakers of Portuguese is like the effect of Robert Burns poetry on native English speakers? Perhaps no one, but I like the analogy anyway. It's poetic.

Also poetic — or so it feels to me, in translation — is the Pope's invitation to expose ourselves to contagious love. Love as disease is a very old metaphor. Lovesick. Fever. But here the idea is an outbreak, an epidemic of love spreading everywhere.

In English, "contagion" feels — at least to me — more positive than "infection," though "infection" is used positively in phrases like "infectious laughter."

Consulting the (unlinkable) OED, I see that one old meaning of "infect" is: "To instil in (someone) an opinion or belief, esp. a pernicious one, as heresy or seditious views. Of an (esp. pernicious) opinion, belief, etc.: to persuade, win over (someone); to seduce. In early use also in a good or neutral sense."

1559   J. Whyte Serm. in J. Strype Ann. Reformation (1824) I. vii. 154   Books..full of pestilent doctrines, blasphemy and heresy, to infect the people.
1588   ‘M. Marprelate’ Oh read ouer D. Iohn Bridges: Epist. 26   Being infected by him with the true knowledge of the gospell.
1660   Exact Accompt Trial Regicides 55   The end of your Speech is nothing, but to infect the People.

This metaphor is important in the understanding the value of freedom of speech. Are we susceptible to infection or does exposure build up our resistance to what is harmful?

There's no verb like "infect" for the English word "contagion," which hampers the translator of "contagiar." But I assume that the Spanish word the Pope used traces back to the Latin word that led to "contagion" and that is  con- together + tangĕre to touch. "Infect," by contrast, comes from the "classical Latin infect-, past participial stem of inficere to dye, to stain, to impregnate, to imbue, to taint, to poison, to affect with disease, to corrupt < in- in- prefix2 + facere to make, do, put.")

That "impregnate" makes me ideate about things Popes say against the use of birth control and the similarity of opening oneself to the contagion of love. But let's not get distracted. The concrete image within "contagion" is touching, and "infection" connotes putting in. That makes "contagion" sound like what women do, and "infection" seems like the way of the man.

But the Pope said "contagiar," so let's look at "contagion," which has as its oldest meaning "The communication of disease from body to body by contact direct or mediate." Figuratively, we see it defined as "Hurtful, defiling, or corrupting contact; infecting influence," a usage that goes back to Chaucer in the 14th century:

c1386   Chaucer Second Nun's Tale 72   My soule..That troubled is by the contagioun Of my body....
1776   Gibbon Decline & Fall I. xxi. 591   His mind was tainted by the contagion of fanaticism.
1836   C. Thirlwall Hist. Greece II. xiii. 190   The contagion of these vices undoubtedly spread through the nation.

A second old figurative use is "Contagious or spreading moral disease; moral corruption," and then, in a positive way, closest to the Pope's meaning, "The contagious or ‘catching’ influence or operation of example, sympathy, and the like."

1781   Gibbon Decline & Fall II. 117   The contagion of loyalty and repentance was communicated from rank to rank.
1863   A. P. Stanley Lect. Jewish Church I. xviii. 397   A contagion of goodness, of enthusiasm, of energy..almost impossible to resist.

ADDED: Some attention should be paid to the idea of "invitation." God/Jesus/the Cross does not infect or produce contagion on its own. Its action is to invite. We have to accept the invitation to get the contagion/infection. It's voluntary. The human mind counts. But if you allow yourself to be touched/impregnated, then you will have something that surpasses the rational mind. These images are very helpful in thinking more generally about freedom of speech and the right to receive the speech of others. Censorship represents the fear of contagion, but if you see the speech as an invitation and the human mind as capable of deciding which beliefs to accept, contagion is less fearsome.
