On the other hand, canons 1124- 1125 and following speak to a mixed marriage (the other party is baptized) and there a permission is needed for the liceity of marriage
. The implicit notion is that enrollment into another Church or ecclesial community not in full communion is effected by baptism.
That is not true, a marriage conducted absent this dispensation is invalid due to Lack of Canonical Form.
You’re mixing apples and turnips.
Canonical Form refers to marrying in the Catholic Church, according to the Catholic Rite in the presence of a priest/deacon or in some cases a lay person appointed by the bishop with Rome’s permission.
As I understand Cameron Lansing’s post, if a priest witnessed the wedding of an Anglican and a Catholic without first obtaining the bishop’s permission for a mixed-marriage (in a diocese where priests can’t grant that permission themselves) the result would be a valid, but illicit, marriage.
OTOH, if he witnessed the wedding of a Catholic and a Salvation Army member, without a dispensation for disparity of cult/worship, the result would be an invalid marriage.
