I would think that if your conscience is that alive you are repentant and perfectly entitled to cling to the cross and share in communion because you sense the scale of the grace that has been applied to you. As you know, your life will never be good enough to see you entitled to sup with Christ so you, like all of the elect, approach the Master’s table as forgiven sinners. I’d hate to vet those receiving communion beyond limiting the invitation to Gospel believing Christians.
