Cheating, seen as equivalent to theft (furtum), turns gambling into a mortal sin (
Salas 1617, dub. 7 no. 1, p. 655;
Cayetan 1525, “Ludus”, fol. 164r). A game also becomes a sin when it is prohibited by local laws (
Soto 1553, pars 1 lib. 4 q. 5 art. 2, p. 313) or misused for gain by playing for high stakes (
Azpilcueta 1556, cap. 19 no. 1, p. 344;
Cayetan 1525, “Ludus”, fol. 164r), giving rise to the sins of avarice and greed (
Azpilcueta 1556, cap. 19 no. 6, p. 346; see
Villalón 1541, cap. 4, fol. 9v). The definition of high stakes depends on each player’s means, because “what is little for one, may be a lot for another” (
Pedraza 1568, lib. 1 cap. 4.32, fol. 85v). A gambling pater familias sets a bad example for his family (
Azpilcueta 1556, cap. 19 no. 3, p. 345; see
Vitoria 1562, pars 2 cap. 2 Mand. 4 par. 1, p. 29). Without aggravating circumstances (scandalum), gambling for gain is regarded as merely a venial sin (
Pedraza 1568, lib. 1 cap. 4.32, fol. 85v;
Azpilcueta 1556, cap. 19 no. 1, p. 344;
Vitoria 1562, pars 2 cap. 2, Mand. 3 par. 1, p. 25), even if local laws forbid gambling altogether: the latter aim at temporal punishment, not at the eternal consequences of a mortal sin (
Azpilcueta 1556, cap. 19 no. 7, p. 346; critical:
Soto 1553, pars 1 lib. 4 q. 5 art. 2, p. 314; considered “probabilior” by
Azor 1618, pars 3 lib. 5 cap. 24, col. 436;
Salas 1617, dub. 2 no. 4,5, p. 642 cites other opinions). Also, social reality cannot be denied: the most exalted persons gamble for large sums, and their confessors invariably absolve them without asking them to quit; if gambling were a mortal sin, such leniency would be impossible (
Azpilcueta 1556, cap. 19 no. 7, p. 346). Professional gamblers, however, are infamous, like robbers, liars, adulterers and murderers (
Mercado 1569, pars 4 cap. 8, fol. 188r-v; see
Villaroel 1738, pars 1 q. 3 art. 3 no. 28, p. 288).
