Well, since you don’t go along with the institution of the Sacramental Priesthood, you obviously have no belief in the Sacramental Real Presence, nor any reason to think “taking” it on your own personal authority would be an offense.
Like you, Biden thinks he has the right to to determine all these things-—true/false, right/wrong, good/evil -— by his own self, independent of the Church. You’re agreed with him on that.
Neither he nor you should approach to receive Christ’s Body and Blood. You know better than to do this. Biden -— he needs to be re-catechized.
Jesus came to deliver us from all that religious mumbo-jumbo and public hoop-jumping.
