If a member gave the sign of the Cross.....

As we know, A catholic will often give the sign of the cross.
The reason is: "It is a very significant prayer because Christians are acknowledging their belief in the triune God, or the Holy Trinity: God the Father, God the Son and God the Holy Spirit."

Several years ago, I was serving communion. Just prior to us taking the elements one of the other servers - (a former Catholic)) gave the sign of the cross.
Granted, I would not expect the pastor to make an "on the spot correction" But should he talk to this individual later - should he bring it up as a point of teacher at some point to the full church? What action should the pastor do /not do?

Now - this happen some 20 years ago - so I dont remember what happened afterwards.

Open for discussion

I like the sign of the cross. I see nothing wrong with this devout practice. It honors the Trinity. Orthodox Christians also use it.

Rom 14:5 One man esteemeth one day above another: another esteemeth every day alike. Let every man be fully persuaded in his own mind.

I do not sign because the Spirit as not laid it on my heart. I see no issue with the practice for good reason. I would ask over coffee.
