In the realm of unconditional Love of Neighbor, yes. Not in the denying Church Teaching on things like Sacraments

Here is what the Church teaches .

From Cardinal Ratzinger (Pope Benedict XVI)
DECLARATION “DOMINUS IESUS”:
ON THE UNICITY AND SALVIFIC UNIVERSALITY OF
JESUS CHRIST AND THE CHURCH

Excerpts..

Furthermore, the salvific action of Jesus Christ, with and through his Spirit, extends beyond the visible boundaries of the Church to all humanity. Speaking of the paschal mystery, in which Christ even now associates the believer to himself in a living manner in the Spirit and gives him the hope of resurrection, the Council states: “All this holds true not only for Christians but also for all men of good will in whose hearts grace is active invisibly. For since Christ died for all, and since all men are in fact called to one and the same destiny, which is divine, we must hold that the Holy Spirit offers to all the possibility of being made partners, in a way known to God, in the paschal mystery”.37

Hence, the connection is clear between the salvific mystery of the Incarnate Word and that of the Spirit, who actualizes the salvific efficacy of the Son made man in the lives of all people, called by God to a single goal, both those who historically preceded the Word made man, and those who live after his coming in history: the Spirit of the Father, bestowed abundantly by the Son, is the animator of all (cf. Jn 3:34).

Thus, the recent Magisterium of the Church has firmly and clearly recalled the truth of a single divine economy: “The Spirit’s presence and activity affect not only individuals but also society and history, peoples, cultures and religions... The Risen Christ ‘is now at work in human hearts through the strength of his Spirit’... Again, it is the Spirit who sows the ‘seeds of the word’ present in various customs and cultures, preparing them for full maturity in Christ”.38 While recognizing the historical-salvific function of the Spirit in the whole universe and in the entire history of humanity,39 the Magisterium states: “This is the same Spirit who was at work in the incarnation and in the life, death, and resurrection of Jesus and who is at work in the Church. He is therefore not an alternative to Christ nor does he fill a sort of void which is sometimes suggested as existing between Christ and the Logos. Whatever the Spirit brings about in human hearts and in the history of peoples, in cultures and religions, serves as a preparation for the Gospel and can only be understood in reference to Christ, the Word who took flesh by the power of the Spirit ‘so that as perfectly human he would save all human beings and sum up all things’”.

Therefore, there exists a single Church of Christ, which subsists in the Catholic Church, governed by the Successor of Peter and by the Bishops in communion with him.58 The Churches which, while not existing in perfect communion with the Catholic Church, remain united to her by means of the closest bonds, that is, by apostolic succession and a valid Eucharist, are true particular Churches.59 Therefore, the Church of Christ is present and operative also in these Churches, even though they lack full communion with the Catholic Church, since they do not accept the Catholic doctrine of the Primacy, which, according to the will of God, the Bishop of Rome objectively has and exercises over the entire Church.60

On the other hand, the ecclesial communities which have not preserved the valid Episcopate and the genuine and integral substance of the Eucharistic mystery,61 are not Churches in the proper sense; however, those who are baptized in these communities are, by Baptism, incorporated in Christ and thus are in a certain communion, albeit imperfect, with the Church.62 Baptism in fact tends per se toward the full development of life in Christ, through the integral profession of faith, the Eucharist, and full communion in the Church.63

“The Christian faithful are therefore not permitted to imagine that the Church of Christ is nothing more than a collection — divided, yet in some way one — of Churches and ecclesial communities; nor are they free to hold that today the Church of Christ nowhere really exists, and must be considered only as a goal which all Churches and ecclesial communities must strive to reach”.64 In fact, “the elements of this already-given Church exist, joined together in their fullness in the Catholic Church and, without this fullness, in the other communities”.65 “Therefore, these separated Churches and communities as such, though we believe they suffer from defects, have by no means been deprived of significance and importance in the mystery of salvation. For the spirit of Christ has not refrained from using them as means of salvation which derive their efficacy from the very fullness of grace and truth entrusted to the Catholic Church”.66

The lack of unity among Christians is certainly a wound for the Church; not in the sense that she is deprived of her unity, but “in that it hinders the complete fulfilment of her universality in history”.67
