For reference, this is what he says on this topic in his book “On Heaven and Earth”:
“Catholic doctrine reminds its divorced members who have remarried that they are not excommunicated — even though they live in a situation on the margin of what indissolubility of marriage and the sacrament of marriage require of them — and they are asked to integrate into the parish life,”
And this is what the catechism says:
“1650 Today there are numerous Catholics in many countries who have recourse to civil divorce and contract new civil unions. In fidelity to the words of Jesus Christ - “Whoever divorces his wife and marries another, commits adultery against her; and if she divorces her husband and marries another, she commits adultery"160 the Church maintains that a new union cannot be recognized as valid, if the first marriage was. If the divorced are remarried civilly, they find themselves in a situation that objectively contravenes God’s law. Consequently, they cannot receive Eucharistic communion as long as this situation persists. For the same reason, they cannot exercise certain ecclesial responsibilities. Reconciliation through the sacrament of Penance can be granted only to those who have repented for having violated the sign of the covenant and of fidelity to Christ, and who are committed to living in complete continence.
1651 Toward Christians who live in this situation, and who often keep the faith and desire to bring up their children in a Christian manner, priests and the whole community must manifest an attentive solicitude, so that they do not consider themselves separated from the Church, in whose life they can and must participate as baptized persons:
They should be encouraged to listen to the Word of God, to attend the Sacrifice of the Mass, to persevere in prayer, to contribute to works of charity and to community efforts for justice, to bring up their children in the Christian faith, to cultivate the spirit and practice of penance and thus implore, day by day, God’s grace.161”
