text: Your question is a good one and worthy of a response. As I see it, the teaching of Amoris Laetitia ch. 8 *qualifies* previous teaching that it is always mortally sinful to divorce, civilly remarry, and be sexually active in that new union. The qualification is that valid mitigating factors (a factor of our Catholic moral tradition) may prompt a person to follow this divorce-remarriage-sexual relationship path and that s/he may choose this path with an informed conscience (also a factor of our Catholic moral tradition) after having undergone the work of discernment of fault, goods, etc. in the internal forum. 
  
  I accept that this is a negation of the universal statement that it is always mortally sinful to divorce, civilly remarry, and be sexually active in the new union. I believe rather that we should have all along been saying that it is *sometimes* mortally sinful to divorce, civilly remarry, and be sexually active in the new union. I do acknowledge that there is a difference here.
