EWTN Catholic Q&A
souls in heaven
Question from lt on 12-28-2012:

You wrote about degrees in heaven and some being able to be closer to God. My father passed away and I believe he has passed purgatory and is now in heaven. If I continue praying for his soul, will he get closer to God in heaven?

Answer by Fr. John Echert on 01-02-2013:

No. The degree of happiness we experience in Heaven is based upon our degree of charity! Which is fixed forever at the moment the soul departs the body.
