An indult Latin Mass will be said on a regular basis soon. If I decide to purchase a 1962 Missal to follow along, is it permissable to buy one that is published by an SSPX publisher (Angelus Press)? There aren’t many other publishers that sell TLM missals.
When the indult goes into effect, the new market will attract Catholic publishers. I would advise you to wait rather than support a schismatic church in any way.
