Well, let me try to make my point clear.
1.In response to ‘not my responsibility’ and ‘mind one’s own business’ attitude I referred to a part of His Holiness message for Lent focused on “
Let us be concerned for each other, to stir a response in love and good works” (Heb 10:24)
Under the subtitle “Let us be concerned for each other”:** responsibility towards our brothers and sisters **The Pope writes/says, ‘All too often, however, our attitude is just the opposite: an indifference and disinterest born of selfishness and masked as a respect for “privacy”. Today too, the Lord’s voice summons all of us to be concerned for one another. **Even today God asks us to be “guardians” of our brothers and sisters (Gen 4:9). **He adds,’ Today, in general, we are very sensitive to the idea of charity and caring about the physical and material well-being of others,
but almost completely silent about our spiritual responsibility towards our brothers and sisters. This was not the case in the
early Church or in those communities that are truly mature in faith.
His Holiness also speaks about
Fraternal Correction and admonishing sinners which is among the
spiritual works of mercy. He says, ‘Christian admonishment, for its part, is never motivated by a spirit of accusation or recrimination.
It is always moved by love and mercy, and springs from genuine concern for the good of the other.’
When I spoke about our duty and responsibility towards our brothers and sisters I had the Lent message in mind especially the reference to fraternal correction and the ancient implied call to be our brothers’ guardians. In the NT we have the great commandment ‘
Love your neighbour as you love yourself’ MT 22:39.
Fraternal correction is ‘deeply rooted in the Scripture and Tradition’ (Prov 9:8, Levit 19:17, Mt 18:15, Gal 6:1, Eph 5:11, 1 Cor 12:25, James 5:20, 1 Timothy 5:20, 2 Thimothy 4:2 …) It is a
demand of charity (Catechism of the Catholic Church 1829)and
an obligation (Catholic Encyclopedia)
“Fraternal correction is not the same as judging others, if it’s done in the spirit of charity and with the intention to help our neighbors “walk more uprightly in the Lord’s ways.” We can never condemn others, or consider ourselves morally superiors,
but we are obliged as Christians to correct others, and allow ourselves to be corrected” From an article on
www.aleteia.org
Capuchin Father Raniero Cantalamessa, the preacher of the Pontifical Household, wrote in a commentary on Matthew 18:15-20, that “there is both active and passive correction.
Not only does the duty to correct exist, but also the duty to allow oneself to be corrected. And here is where one sees if one is sufficiently mature to correct others.” aleteia.
2 I still advice the OP, since he has good reasons (and not just ‘assuming’) to think his friend needs to go to confession before receiving the Holy Eucharist, to approach him and talk to him, not accusingly but charitably. A counsel done with love and out of love will surely bear good fruits
Peace,
