Well, according to current canonical law, there are no more minor orders in canon law. They were unfortunately abolished by Pope Paul VI. However, some communities, such as the so-called "Ecclesia Dei" communities, and formerly the Society of Pious the Tenth, continue to maintain the minor orders with the permission of Rome. But the tonsure and minor orders no longer incorporate you into the clerical state according to current canon law. In the old canon law, yes, you were incorporated into the clerical state, but the old canon law is no longer in effect.
Therefore, you are not obliged to wear the cassock according to the new canon law, because the new canon law states that only deacons, upon ordination, become members of the clergy. As a member of the clergy, you have the obligation to wear clerical dress. So, according to current canon law, you would not be obligated to wear the cassock unless you are a member of a religious community and have made vows or promises, and your congregation requires you to wear it. In that case, you must obey.
But I don't think this is the question you're asking, because you're referring only to the former minor orders. From this point of view, we are not obliged to wear it. Perhaps it would be better, if you are outside the seminary and spending time away for other reasons, to avoid confusion. It's not necessarily bad, but it depends on the situation. If people already know you were in the seminary and are simply taking a time of reflection with the intention to return, I think you can wear the cassock. Ultimately, it depends on your personal situation and the parish where you are.
Dear visitors of Gloria Dei and all who have already written or who will write a personal message to me. I am grateful for your attention, your kindness, for your spiritual support and especially for your sacrifices and prayers for me. God may reward you!
