Short answer
Stop wearing or displaying crosses, statues, icons and other symbols of worship, since a Muslim's body and home should not carry the signs of another faith. Items that belong to family members can go back to them; your own can be disposed of quietly, never smashed or mocked in front of anyone. A Bible can be kept with respect, and family photos and keepsakes are fine.
Wearing a cross or another religion's symbol is haram, and wearing it to show belonging to that religion is kufr in the Hanafi texts, which discuss the zunnar (belt worn as a religious sign) in this way. Statues and pictures of living beings kept on display are not allowed in the home. Religious items should not be insulted or destroyed in a way that hurts others.
The four schools agree on this.
Explanation
Aisha reported that the Prophet ﷺ would not leave anything in his house bearing cross shapes without removing them. He also said angels do not enter a house with images. So a Muslim home has no crosses, statues, icons or pictures used in worship. This is not hostility to Christians; it is part of keeping a home for the worship of Allah alone.
- Cross necklace: stop wearing it. Gold or silver can be melted down or reshaped into something else. If it is a family heirloom, some muftis allow returning it to the relative it came from rather than destroying it.
- Statues, icons, nativity sets, rosaries: if they belong to family members, give them back. Your own should be disposed of quietly, not sold or passed to others for worship.
- Paintings of Jesus or Mary: take them down, and return them to family if they want them.
- Bible: you may keep it on a shelf with respect. See can Muslims read the Bible.
- Photos and keepsakes: wedding photos taken in a church, baptism certificates and family albums can be kept as memories.
How you do it matters as much as what you do. Do not smash or burn things in front of your family, or throw them in the bin where they will find them. The Quran forbids insulting what others hold sacred. Quietly offering items back to the people who value them protects your family's feelings and shows them the gentleness of Islam. See telling your family.
The evidence
Quran, Surah Al-An'aam 6:108
وَلَا تَسُبُّوا۟ ٱلَّذِينَ يَدْعُونَ مِن دُونِ ٱللَّهِ فَيَسُبُّوا۟ ٱللَّهَ عَدْوًۢا بِغَيْرِ عِلْمٍۢ ۗ كَذَٰلِكَ زَيَّنَّا لِكُلِّ أُمَّةٍ عَمَلَهُمْ ثُمَّ إِلَىٰ رَبِّهِم مَّرْجِعُهُمْ فَيُنَبِّئُهُم بِمَا كَانُوا۟ يَعْمَلُونَ ﴿١٠٨﴾
And do not insult those they invoke other than Allah, lest they insult Allah in enmity without knowledge. Thus We have made pleasing to every community their deeds. Then to their Lord is their return, and He will inform them about what they used to do.
Religious items are handled without insult.
Sahih al-Bukhari 5952
Sahih... لم يكن يترك في بيته شيئا فيه تصاليب إلا نقضه ...

A Muslim home does not display crosses.
Sahih al-Bukhari 3225
Sahih... لا تدخل الملائكة بيتا فيه كلب ولا صورة ...
"The angels do not enter a house in which there is a dog or an image."
Images and statues are not kept on display.
Where the ruling is recorded
- al-Fatawa al-Hindiyya, Kitab al-Siyar, the chapter on the rulings of apostates. Wearing the distinctive religious sign of another faith to show belonging to it is disbelief.
