There has recently been some public mockery of our faith [1] [2]. We need to pray and make reparations for the blasphemies and sacrileges committed. However, we should also energetically rebuke the offenders by instructing them that what they are doing is wrong and that they should stop mocking our faith.
Jesus’ teaching about ‘turning the other cheek’ in the Sermon on the Mount (Matthew 5:38-39) refers to not being vengeful, to never repay evil with evil, as Saint Paul also teaches in Romans 12:17.21.
Nevertheless, Jesus also rebuked and drove the sellers and the moneychangers out of the Temple with a whip, overturning their tables (Mark 11:15-16) (John 2:14-16). So, when someone mocks or shows irreverence toward our faith, we cannot remain silent as if nothing has happened. Instead, we should call their attention by telling them that what they are doing is wrong and that they should stop doing such things. We should rightfully rebuke them, but without insulting them or mocking them in return; otherwise, we would be sinning by repaying evil with evil.
Let’s also recall that Jesus responded when He was slapped in the face (John 18:22-23). That was a slap to the Face of God. Therefore, when our Lord is slapped, we cannot remain silent. Furthermore, ‘Admonishing the Sinner’ and ‘Instructing the Ignorant’ are some of the spiritual works of mercy.

the reproach of Christ 
in these terrible sinful times we live in, a layperson gently rebuking a sinner who blasphemies the Catholic faith, is challenging to say the least. Even within your family and relatives, can lead to strained relationships. What I tell them you have the right to disagree with the Church’s teachings but to then curse the Church and the Pope is like you insulting my parents and home as God is my father also and Virgin Mary is my mother too. That makes them stop and ponder their sinful words.
Hi Ron, as I always understood it “turning the other cheek” is also a sign of defiance toward your adversary. By offering the other side you are basically telling the mocker that what he did was wrong.
I would not say “defiance”, but it is a case of not resisting certain type of evil, as long as there is no sin for yourself, nor is anyone else led into sin. We accept some unjust harm without repaying harm for harm.
[Romans]
{12:17} Render to no one harm for harm. Provide good things, not only in the sight of God, but also in the sight of all men.
{12:18} If it is possible, in so far as you are able, be at peace with all men.
[1 Thessalonians]
{5:15} See to it that no one repays evil for evil to anyone. Instead, always pursue whatever is good, with one another and with all.
