Quoted from Ed Peters canon law blog:
"A) I think the pope’s statement reflects a mistaken assumption, common among those who were trained under the 1917 Code, that priests with normal faculties for Confession still cannot absolve from the sin (let alone from the crime) of abortion. I and others, however, hold that all priests with faculties can absolve from this sin. The pope’s comments resolve this debate admirably (at least for the period of the Jubilee Year) as I happen to think it should be resolved.
B) The pope’s statement seems to assume that the sin of abortion and the crime of abortion are concomitant realities. I, however, and I’ll wager nearly all other experts, hold sin to be distinguishable from crime, and that this crime is rarely, if ever, committed by women (again, as opposed to abortionists)."
In sum, it appears that the Pope’s recent statement merely reaffirms the existing long standing practice in most parts of the world.
