There is no automatic sin in divorce, NONE at all.
Those who think otherwise are probably committing a sin, themselves, however.
Really???? Didn’t Jesus say “what God has joined together, let no man put asunder”?
Couldn't those who think otherwise simply be honestly wrong, but with good intentions?
Ne zot, it sure is obvious when someone's personal buttons are pushed ...
Both of these statement are very incomplete, just as it is scandalously incomplete to say there is no sin in killing someone. Scandal leads people to sin. In the U.S., most divorces are issued for no-fault reasons where one simply chooses to renege on marital obligations. Those who force no-fault on their spouse are in grave sin and cannot receive Holy Communion unless they repent and have a firm resolve to stop the sin (i.e. reconcile and restore intact home).
However, in the minor number of cases where there is a morally licit reason for separation of spouses, the spouse who is innocent must (according to canon law) have the bishop's permission before seeking civil divorce or separation (canon 1692, 1151-1155).
So, for those who are divorced, about half are in grave manifest objective sin. No-fault abandoners and abusers should not be given Communion, until after they stop the grave sinning.
