Translation of "adequately" into Latin

The only point that needs mentioning here is that for celebrating the second form there should be an adequate number of confessors present.

Satis hic monere sit ad illius formae celebrationem praesentiam sufficientis numeri astantium conferre.

Indeed, the message of salvation encounters many obstacles stemming from erroneous concepts and a serious lack of adequate formation.

Etenim, nuntium salutis impedimenta multa invenit ex erroneis rerum notionibus necnon ex gravi institutionis idoneae penuria.
