'...but instead read it at home (for those that do not have a TLM available to them) ... What do you use for this?'
Any pre-Vatican II Missal will do. My family and I use the St. Andrews Daily Missal, for instance.
'Currently we attend Mass at the Shrine of the Most Blessed Sacrament - but in rare circumstances when we are unable to attend the Mass our only other option (at this time) is the local NO parish which my husband has said we will not attend for any reason.'
Good for him. Avoid it like the plague.
'We've decided to pray the Mass at home on those days when we cannot attend Mass. But I'm wondering what resource would be best for this. We have a 1962 Missal - but I'm not sure how to properly use it.'
Have your husband read through it as if he were standing in for a priest. He is not, of course, a priest and cannot consecrate a host, etc. However, he can and should lead your family prayers which would include praying the Mass at home.
Another note, as you wont be making Confession or receiving Communion at home, you could try to make an Act of Contrition before you read the Mass and, at the time when you would be taking Communion, make a 'spiritual Communion' (a prayer expressing your intent to receive Communion), as it were. Again, the St. Andrews I have includes that a prayer for that purpose.
'I don't give a sermon!'
I dont either. My personal opinion is that, that would be 'going too far'. However, I do read the Epistle and the Gospel in English and not Latin, because they are 'lessons', in a sense. I also read the introduction to each day's propers, which usually gives some sort of historical context concerning what is being prayed and why.
'I think also, any kind of spiritual reading or extra decades of the rosary, over and above what you'd normally do, is acceptable instead of the missal (or as well as).'
I would hasten to clarify that I wouldnt use 'any' kind of spiritual reading. Any Catholic spiritual reading, perhaps, but not as a part of the Mass. I'd do it before or after.
If you have a Breviary or a Monastic Diurnal, etc. you can pray the Divine Office. If you have a Raccolta, etc. you could research and include some prayers appropriate to the particular day or season. There are also Chaplets that you can pray, such as St. Michael's Chaplet, St. Joseph's Chaplet, etc.
