TRADCATKNIGHT: LENT: TRIFLING WITH GOD by the Priests of the Congregation of St. Paul, 1893
A Holy writer, commenting upon this Gospel, says that the seven devils spoken of are the relapsing sinner's sevenfold wickedness in his contempt of the seven gifts of grace from the Holy Ghost which wrought his former conversion.
To relapse into sin is to sin against the special light which one always receives in the hour of conversion. It adds to the new sin the sin of ingratitude, and the breaking of one's solemn promise made to God, when in confession, to avoid the occasions of sin in the future and to amend one's life. After a good absolution one goes forth not only with a clear conscience, but with a clearer mind. He sees things in a new light, as we say, and wonders how he could ever have been either so wicked or so foolish as to commit the sins he has just confessed.
